5.37 + x =12.89 explanation please it’s two step equation
Answer:
7.52
Step-by-step explanation:
5.37 + x = 12.89
In order to solve this equation, we must isolate the variable, x.
1.) To do this, subtract 5.37 on both sides of the equation.
5.37 + x = 12.89
-5.37 -5.37
x = 7.52
Therefore, x = 7.52
Answer:

Corry collects cube containers. She fills them with water and pours them into a rectangular prism. She was playing with them and discovered something interesting. She had three cube containers. One cube was 1 inch by 1 inch by 1 inch. A second cube was 2 inches by 2 inches by 2 inches and a third cube was 3 inches by 3inches by 3 inches.
She filled all three with water. Then Corry poured all three cubes into a rectangular prism filling it exactly! The rectangular prism has a square base with a side length (1+2+3 = 6) inches and the height is 1 inch.
Corry wonders whether she has found a pattern. Investigate using more cube containers to fill square base prisms with heights of 1 in. Describe any conjectures you discover.
Corry's conjecture is right, and the volume follows a pattern
The volume of a cube of side length l is:
[tex]V = l^3[/tex]
For the first cube of length 1 in, the volume is:
[tex]V = 1^3[/tex]
[tex]V = 1[/tex]
For the second cube of length 2 in, the volume is:
[tex]V = 2^3[/tex]
[tex]V = 8[/tex]
For the third cube of length 1 in, the volume is:
[tex]V = 3^3[/tex]
[tex]V = 27[/tex]
So, the total volume is:
[tex]Total =1 + 8 + 27[/tex]
[tex]Total =36[/tex]
The volume of a rectangular prism of base lengths 6 in and height 1 in is:
[tex]Volume = 6^2 \times 1[/tex]
[tex]Volume = 36[/tex]
Assume, he adds a cube of side length 4 in, the volume is:
[tex]V = 4^3[/tex]
[tex]V = 64[/tex]
The total volume would be:
[tex]V =36 + 64[/tex]
[tex]V =100[/tex]
The base length of the rectangular prism would be:
[tex]Length =1+2+3+4[/tex]
[tex]Length =10[/tex]
The volume of the rectangular prism would be:
[tex]Volume = 10^2 \times 1[/tex]
[tex]Volume = 100[/tex]
So, the pattern is:
Cubes Volumes
1, 2, 3 36
1, 2, 3,4 100

What is the equation of the line that passes through the point (-4,-3)(−4,−3) and has a slope of \frac{3}{4}
Answer:
y = 3/4x
Step-by-step explanation:
Given:
x1 = -4
y1 = -3
slope (m) = 3/4
Solution:
y - y1 = m ( x - x1 )
y - (-3) = 3/4 ( x - (-4) )
y + 3 = 3/4 ( x + 4 )
y + 3 = 3/4x + 3
y = 3/4x + 3 - 3
y = 3/4x

B
ASA
SAA
neither
Help plz
Answer: I’m pretty sure it’s SAA
Step-by-step explanation: if it were ASA the side would be in between the two congruent Angles but that’s not the case here. And it has enough information so it’s also not neither.
The statement that proves that the triangles are congruent is SAA
From the figure, we have the following highlights
A corresponding side (S) on both triangles is equalTwo corresponding angles (AA) beside one another are also equalThis means that, the congruent statement is SAA i.e. Side-Angle-Angle
Hence, the statement that proves that the triangles are congruent is SAA

A store sells hardcover books for $8 and paperback books for $5. You buy 7 books, represented by the equation x + y = 7, where x is the number of hardcover books and y is the number of paperback books. The equation 8x + 5y = 41 represents the total cost. How many of each type of book did you buy?
Answer:
Total number of Hardcover books is TWO while the number of Paperback books is FIVE
Step-by-step explanation:
No. of hardcover book = x
No. of paperback book = y
Cost of one hardcover book = $8
Cost of one paperback book = $5 We are given that:
x+y=7 (Equation 1)
8x+5y=41 (Equation 2)
We can find out value of x and y by solving both equations simultaneously.
Hence, Total number of Hardcover books is TWO while the number of Paperback books is FIVE

Answer:
S (2, - 15 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Using (x₁, y₁ ) = T (0, 3 ) and (x₂, y₂ ) = S (x, y )
Calculate the midpoint using above and equate to coordinates of (1, - 6 )
[tex]\frac{x+0}{2}[/tex] = 1 ( multiply both sides by 2 )
x = 2
[tex]\frac{y+3}{2}[/tex] = - 6 ( multiply both sides by 2 )
y + 3 = - 12 ( subtract 3 from both sides )
y = - 15
S has coordinates (x, y ) = (2, - 15 )
Answer:
Point S is at the ordered pair (2,-15)
Step-by-step explanation:
midpoint formula : midpoint ordered pair (x,y) = ( [tex]\frac{x1+x2}{2}[/tex],[tex]\frac{y1+y2}{2}[/tex])
midpoint x = [tex]\frac{x1+x2}{2}[/tex] ; midpoint y = [tex]\frac{y1+y2}{2}[/tex]
midpoint x = 1 x1 = 0 midpoint y = -6 y1=3
Solve each equation for x2 and y2 to get the points for S.
x = [tex]\frac{x1+x2}{2}[/tex]
1 = (0) +x2 / 2
2 = x2
y = [tex]\frac{y1+y2}{2}[/tex]
-6 = 3 + y2 / 2
-12 = 3 + y2
-15 = y2
(2,-15) are the coordinates to point S.
Use the distance formula to answer the question:
What is the distance between (5,9), (1, 6)?
Step-by-step explanation:
The formula is Distance=√(x2-x1)²+(y2 -y1)²
x1 is 5, x2 is 1, y1 is 9, y2 is 6
D = √( 1-5)² +(6-9)²
D = √(-4)²+(-3)²
D = √16+9
D = √25
D = 5 units

Answer:
Hello There!
Your question says that
[tex]7 \frac{1}{3} \times \frac{7}{11} [/tex]
Now lets convert mixed fraction to improper fraction
[tex]7 \frac{1}{3} \\ \\ so \: 7 \times 3 + 1 = 22 \\ \\ so \: \frac{22}{3} [/tex]
Now let's simplify..
[tex] \frac{22}{3} \times \frac{7}{11} \\ \\ [/tex]
Now simplify 22 and 11 so it will look like
[tex] \frac{2}{ 3} \times \frac{7}{1} \\ \\ multiply \: \frac{2 \times 7}{3 \times 1} \\ \\ = \frac{14}{3} [/tex]
Now lets convert it to mixed fraction...
[tex] \frac{14}{3} = 4 \frac{2}{3} \\ \\ [/tex]
So it is the answer
[tex]4 \: \frac{2}{3} \\ \\ [/tex]

how much is 75 decreased by 8% ???
Answer:
69
Step-by-step explanation:
The number 75 decreased by 8% means that you are looking for 92% of 75. To find a percent of the number you can multiply a number by the percent in decimal form. So, to find 92% of 75, multiply 75*0.92. This gives you 69. Doing this is the same as finding 8% of 75 and then subtracting.
