Answer:
C. Multiply the bottom equation by 2
Step-by-step explanation:
-2x+ 4y= 10
3x- 2y =-7
We want to multiply the second equation by 2
-2x+ 4y= 10
6x- 4y =-14
------------------
4x +0y = -4
Step-by-step explanation:
= 4,830 - 3,57 × 10³
= 4,83 - 3,57 × 1.000
= 4,83 - 3.570
= -3.565,17
= -3,56517 × 10³
≈ -3,57 × 10³
Answer:
63 feet
Step-by-step explanation:
perimeter is the sum of all four sides and, since it's a square then all sides are equal
to find how long each side is divide 252 by 4
252÷4 = 63
Okay act like 6:8 is 6/8 you could either simplify the fraction or multiply to make it bigger
3:4 (divide by 2)
12:16 (multiply by 2)
18:24 (multiply by 3)
24:32 (multiply by 4)
Answer: 1/4:1 1/4 = 2:b
↓
1/4 / 5/4 = 2/b
4/4 * 5 = 2/b
1/5 = 2/b
b/5 = 2
b = 2 * 5
b = 10
