PWEASE help me (7th grade math work) will mark as a Brainliest and pls show work

-6 = -1/2(9) + B

-6 = 4.5 + B

-6--4.5 = B

-1.5 = B

B= -1.5

y=-1/2x - 1.5

y=-1/2(9) - 1.5

y= -4.5-1.5  

y=-6

Answer:

for the first one its x=30

for the second one its x=6

Step-by-step explanation:

its x=30 because at the end if you do the problem yourself, you would have to multiply 5×6 which is 30.

im not sure why its x=6 on that one i might be wrong but i did it but im also confused on it but i tried so yeah maybe it is.

Answer:

x = 94°

Step-by-step explanation:

interior angle sum of any polygon: (s-2)×180°

with s being the number of sides.

since there are 7 sides, 7-2 = 5

5* 180°

900° = total sum

______________________________

since we know the rest of the angles, just subtract the total sum from the sum of the known angles to find the unknown one.

900°-(148°+140°+136°+142°+150°+90°) = x

900°- 806°= 94°

x= 94°

The ratio of the perimeters of 2 similar shapes is the sidelength of 1 shape to the matching sidelength. That means the ratios of the perimeters are 10:6 = 5:3

The ratio of areas = ratio of perimeters ^2 --> 25:9

Ratios of areas = ratios of perimeters ^2

Answer:

Hi again I helped you on your last question, I love helping people. Anyway here's the answer!

16. 0.188 rounded nearest hundredth = 0.19

17.  0.455 rounded nearest hundredth = 0.46

18. 0.538 rounded nearest hundredth = 0.54

19. 0.417 rounded nearest hundredth = 0.42

20. 2.833 rounded nearest hundredth = 2.83

21. 3.667 rounded nearest hundredth = 3.67

Answer:

A

Step-by-step explanation:

Because your not studying

Answer:

D

Step-by-step explanation:

simple plug and chug.

Understand that variables are already defined, x=3/4, y=15 meaning that if we plug one of the variables into an equation, we should obtain the other variable's number.

y=20x will result in y=15 when x=3/4 and vice versa.

Answer:

887.40

Step-by-step explanation:

amount = principal(1i)^n

i = .0425/2 = .02125 , n = 8 , principal = 750

amount = 750(1.02125)^8 = 887.40

Answer:

The difference is elevation is 457 feet.

Step-by-step explanation:

You simply add the two numbers together.

Answer:

23%

Step-by-step explanation:

She sorted using decimal values.

We convert the decimals to percent

.17 of her 100 pieces were black licorice.

.17 = 0.17 × 100 = 17%

.42 were m&m = 0.42 × 100 = 42%

.12 were skittles. = 0.12 × 100= 12%

.09 were smarties = 0.09 × 100= 9%

.14 were lollipops = 0.14 × 100 = 14 %

.06 were gum drops. = 0.06 × 100= 6 %

Mrs. Potter decided to bring the black licorice and the gum drops to school. What percent of her candy did she bring to school?

Licorice = 17%

Gum drops = 6%

The percent of her candy that she brought to school = 17% + 6%

= 23%

The percent of her candy that she brought to school is 23%

Answer: 76.701 x 76.701 ≈ 5883

Step-by-step explanation: Estoy seguro de que eso es todo

Answer:

30Cals

Step-by-step explanation:

150/30*6

Easy.

Answer:

Plug in what you are given for y then solve for x:

[tex]-2 + 2 = -3(x - 4)\\\\0 = -3(x - 4)\\\\0 = -3x + 12\\\\-12 = -3x\\\\4 = x[/tex]

The missing value would be 4.

Answer:

Step-by-step explanation:

the sum of angles of triangle=180 degrees

one angle=90 degrees

180-90=90 degrees is the measure of the other two angles

since the two angles are congruent or equal

90/2=45 degrees

the measure of the 2 angles =45 degrees each

Answer:

-47.4

Step-by-step explanation:

Answer:

23.55

Step-by-step explanation:

To calculate the area I did the following equation

area = 3.14 (r) (r)

area = 3.14 (3) (3)

area = 28.26

The area is 28.26 but the question is asking how much gravel would be needed to fill 5/6 of the area.

The equation for 5/6 out of 28.26 is

28.26 (5/6) = 23.55

So the final answer is (a.) 23.55 sq. ft.

Could you please show me a graph so I can answer more clearly? I'll follow up on this question if it helps.

Step-by-step explanation:

Answer:

B.

Step-by-step explanation:

Supplementary angles have a sum of 180 degrees, and those two angles added to angle 1 would be equal to 180 degrees since they are straight lines.

Answer:

C

Step-by-step explanation:

Supplementary - adds up to 180

Lets answer the information by making it look like a budget subtraction:

60 = Total

1. Remove the delivery cost, so you can leave the rest of the budget for your pizzas.

60 - 7.50 = 52.50

2. Now, subtract the cost of pizzas multiple times until you reach it to where you dont have enough for another pizza.

52.50 - 14 = 38.50  Pizza 1

38.50 - 14 = 24.50  Pizza 2

24.50 - 14 = 10.50  Pizza 3

Now, theres not enough to buy another.

So, we know that Jacque can only afford 3 pizzas, but she need to calculate the number of slices.

3. Multiply the number of slices by the number of pizzas.

8 x 3 = 24

So, the largest number is 24 slices.

Answer:

The points on a line can be assigned real number coordinates (think of numbers on a number line). The distance between any two points is their difference.

The solution to the problem is 16.

first, you must set up the equation.

[tex]4^4*\frac{4^3}{4^5}[/tex]

Then, simplify exponents.

256*[tex]\frac{64}{1024}[/tex]

Next, simplify the equation.
