Part A: Solve −mk − 90 > 85 for m. Show your work. (4 points) Part B: Solve 3c − 5f = 55 for f. Show your work. (6 points) (10 points)
Answer:
m < -175/k
f = -11 + [tex]\frac{3}{5}[/tex]c
Step-by-step explanation:
Part A:
-mk - 90 > 85
add 90 to each side to get:
-mk > 175
divide each side by -k to get:
m < -175/k
(inequality symbol switched because we divided by a negative)
Part B:
3c - 5f = 55
subtract 3c from each side to get:
-5f = 55 - 3c
divide each side by -5 to get:
f = -(55 - 3c) / 5 or -11 + [tex]\frac{3}{5}[/tex]c

Solve for r.
4r–3r=20
r=
Answer:
20
Step-by-step explanation:
4r - 3r = 20
r = 20
There you go.
Answer:
r = 20
Step-by-step explanation:
Let's solve your equation step-by-step.
4r − 3r = 20
Step 1: Simplify both sides of the equation.
4r − 3r =20
4r + −3r =20
(4r + −3r) =20 (Combine Like Terms)

How do you write 8 whole and 1/2 + whole 7 2/3 as a mixed number
The answer is 16 1/6
Step-by-step explanation:
1. make both of the denominators into six : 1/2=3/6 and 2/3=4/6
2. add them all together 8+7=15, 4/6+3/6=7/6
3. make the 7/6 into a mixed number so 1 1/6 add that to the 15 so 16 1/6
Answer: 16 1/6
To add mixed numbers, the first thing you do is convert the mixed numbers into improper fractions. How?
You multiply the whole number with the denominator of the proper fraction, then you'll add the numerator.
First mixed number is 8 1/2.
So, you'll multiply 8 by 2 then add 1.
(8 × 2) + 1 = 17
Next is 7 2/3.
Repeat this process.
(7 × 3) + 2 = 23
When your done, plug in the denominator and find the LCD, since the denominators are unlike. (First find the LCM of 2 and 3, which is 6). Our improper fractions should be:
8 1/2 = 17/2 × 3/3
7 2/3 = 23/3 × 2/2
Multiply the LCD, which is 2 and 3 and you'll get:
LCD of 8 1/2 ⇒ 51/6
LCD of 7 2/3 ⇒ 46/6
Now we can add. (You DO NOT add the denominator).
51/6 + 46/6 = 97/6
Since 97/6 is an improper fraction, we must convert it into a whole number.
Divide 97/6 and you'll get 16 with a reminder of 1.
16 is the whole number.
1 is the numerator.
Hence, the answer is 16 1/6.

x=6
[tex]\\ \sf\longmapsto y=3(6)+10=18+10=28[/tex]
Step-by-step explanation:
y = 3x + 10
x = 4, 5, 6Soo :
y = 3(4) + 10 = 12 + 10 = 22
y = 3(5) + 10 = 15 + 10 = 25

The perimeter of a triangle is 71 cm. If the longest side of the triangle is 8 cm longer than five times the shortest side and the third side is 7 cm less than four times the shortest side. How long is the longest side of the triangle?
Answer:
43 cm
Step-by-step explanation:
If the longest side of the triangle is 8 cm longer than five times the shortest side
5s + 8
the third side is 7 cm less than four times the shortest side
4s - 7
The perimeter of a triangle is 71 cm
s + (4s - 7) + (5s + 8) = 71
Combine like terms
10s + 1 = 71
Subtract 1 from both sides
10s = 70
divide both sides by 10
s = 7
---------------------------------
How long is the longest side of the triangle
5s + 8
5(7) + 8
35 + 8

B.-4
C. 4
D. 36
Answer:
C: 4
Step-by-step explanation:
We can rearrange the numbers:
[tex]-16+20=+20-16=20-16=4[/tex]
Answer:
C. 4
Step-by-step explanation:
-16+20 equals 4 becase:
-16 is under zero, and if we add 20 to that, it will take 16 of that 20 to fill up the negative part, and the rest part remaining will be 4. So that four will add up to be the positive number!

Dylan went to the toy store and
bought 3 action figures for $45.
How much did 1 action figure
cost?
*Use the dollar sign"

Using the information from
problem #9, write the equation.
What is the equation?
Answer:
15$
Step-by-step explanation:
45 ÷ 3 = 15
The value in cents of a nickels, The value in cents of a dimes =, The value in cents of a quarters = , The value in cents of a dimes and one quarter = ,The value in cents of 13 dimes =
The value in cents of a nickels = 5a
[] A nickle is worth 5 cents, so 5a is the value of a nickles
The value in cents of a dimes = 10a
[] The value of a dime is 10 cents, so 10a is equal to a dimes
The value in cents of a quarters = 25a
[] A quarter is worth 25 cents, so 25a is the value of a quarters
The value in cents of a dimes and one quarter = 10a + 25
[] Up above we figured out the expression for a dimes, so we need to add 25 to it for one quarter
The value in cents of 13 dimes = 130
[] A dime is worth 10 seconds, so 13 * 10 = 130

A store is having a sale on trail mix and jelly beans. For 3 pounds of trail mix and 8 pounds of jelly beans, the total cost is $31. For 5 pounds of trail mix and pounds of 2 jelly beans, the total cost is 12. Find the cost for each pound of trail mix and each pound of jelly beans.
Answer:
trail mix costs 1.00 per pound
jelly beans costs 3.50 per pound
Step-by-step explanation:
t = cost of trail mix
b = cost of jelly beans
3t+8b = 31
5t+2b = 12
Multiply the second equation by -4
-4(5t+2b = 12)
-20t+-8b = -48
Add this to the first equation
3t+8b = 31
-20t+-8b = -48
-------------------------
-17t = -17
Divide by -17
t = 1
Now we can find b
3t+8b = 21
3(1) +8b = 31
3+8b =31
Subtract 3
8b = 31-3
8b = 28
Divide by 8
b = 28/8
b = 7/3
b = 3.50
Let trail mix be x and jelly beans be y
The equations are
3x+8y=31-(1)5x+2y=12-(2)Multiplying (1) by 1 and (2) by 4
3x+8y=31---(3)20x+8y=48--(4)Subtracting
[tex]\\ \sf\longmapsto -17x=-17[/tex]
[tex]\\ \sf\longmapsto x=1[/tex]
Putting in eq(2)
[tex]\\ \sf\longmapsto 5(1)+2y=12[/tex]
[tex]\\ \sf\longmapsto 2y=7[/tex]
[tex]\\ \sf\longmapsto y=7/2[/tex]

Find the slope of the line that goes through the points (4,-3) and (5,0)
Answer:
the slope of the points (4,-3) and (5,0) is 3
Step-by-step explanation: I used the formula y2-y1 over x2-x1 will give you the answer hope this helped!
Answer:
[tex]\boxed {\boxed {\sf m=3}}[/tex]
Step-by-step explanation:
We are asked to find the slope of the line that passes through (4, -3) and (5,0).
The slope is the number that tells us the steepness and direction of a line. It is the rise over run, or the change in y over the change in x.
[tex]m= \frac{ \Delta y}{\Delta x} = \frac{y_2-y_1}{x_2-x_1}[/tex]
In the slope formula, (x₁, y₁) and (x₂, y₂) are the points the line passes through. The points we are given are (4, -3) and (5,0). If we match the value with its corresponding value, we see that:
x₁ = 4 y₁ = -3x₂ = 5 y₂ = 0Substitute the values into the formula.
[tex]m= \frac{0 - -3}{5-4}[/tex]
Solve the numerator. Remember that 2 back to back subtraction signs become an addition sign.
0--3 = 0+3=3[tex]m= \frac{3}{5-4}[/tex]
Solve the denominator.
5-4 =1[tex]m= \frac{3}{1}[/tex]
Divide.
[tex]m=3[/tex]
The slope of the line is 3.

what is the measure of angle x
Answer:
180
Step-by-step explanation:
Find the value of X in triangles by subtracting known angle measurements from 180 degrees. Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle.
