Answer:
C. 25 ÷ 10
Step-by-step explanation:
A. 10/25
B. 2/5
C. 25 ÷ 10
D. 0.4
Total customers at Becky's restaurant = 25
Customers who order wheat rolls = 10
It means 10 out of 25 customers order wheat rolls
That is
10 / 25
Dividing both numerator and denominator by 5
= 2 / 5
2/5 in decimal
= 0.4
The option Which does NOT represent the part of the customers who order wheat rolls
is 25/10
Option C. 25 ÷ 10
The answer is D or the fourth choice, 12
Answer:11 miles
Step-by-step explanation:
Answer: y=(-3x+7)/2
Isolate y.
2y= -3x+7
y= (-3+7)/2
Answer: x=(-2y+7)/3
Isolate x
3x=-2y+7
x=(-2y+7)/3
Answer: 6x+4y=14
Idk if that counts but multiply the whole equation by 2.
<u>Answers</u>
1. (3 + xz)(–3 + xz)
2. (y² – xy)(y² + xy)
3. (64y2 + x2)(–x2 + 64y2)
<u>Explanation</u>
The difference of 2 squares is in the form (a+b)(a-c).
<span>(3 + xz)(–3 + xz) = (3 + xz)(xz -3)
= (xz + 3)(xz - 3)
= x</span>²y²-3xy+3xy-9
<span> =x</span>²y² - 3²<span>
(y</span>² – xy)(y² + xy) = y⁴+xy³-xy³-x²y²
<span> = y</span>⁴ - x²y²
<span>
(64y2 + x2)(–x2 + 64y2)= (64y</span>²+x²)(64y²-x²)
= 4096y⁴-64y²x²+64y²x²-x⁴
= 4096y⁴ - x⁴
