Answer:
D) Multiply A by -4 and B by 5
Step-by-step explanation:
5x-2y=10
4x+3y=7
----------------
-4(5x-2y)=-4(10)
5(4x+3y)=5(7)
----------------------
-20x+8y=-40
20x+15y=35
---------------------
23y=-5
y=-5/23
5x-2(-5/23)=10
5x+10/23=10
5x=10-10/23
5x=230/23-10/23
5x=220/23
x=(220/23)/5
x=(220/23)(1/5)
x=220/115
x=44/23
Answer:The number of angles & sides is always the same.
Step-by-step explanation:
Answer:
Sarah makes 8 rows of squares.
Step-by-step explanation:
Given:
Number of squares she uses = 48
Number of squares in each row = 6
We need to find the number of rows she can makes.
Solution:
Let the number of rows she can make be
.
Now we can say that;
Number of rows she can make is equal to Number of squares she uses divided by number of squares in each row.
framing in equation form we get;

Hence Sarah makes 8 rows of squares.
