Answer:
x = 18 y = 10
Step-by-step explanation:
let the first number be x
let the second number be y
x = y + 8..... equation 1
2x + y = 46.... equation 2
x is the larger number
y is the smaller number.
Rearrange the equation and add equation 1 to equation 2.
x - y = 8
+ 2x + y = 46
-------------------
3x + 0 = 54
3x = 54
divide both sides by 3
x = 54/3
x = 18
Substitute x = 18 into equation 1
x = y + 8
18 = y + 8
collect like terms
y = 18-8
y = 10

What the triangle format? what does it look like? it all depends.
Answer:
Step-by-step explanation:
When you simplify the numerator and the denominator, you find they both have denominators of xy. So, the ratio of those is the ratio of their numerators.
<u><em>Answer: x⁷</em></u>
Step-by-step explanation:
distributive property: a(b+c)=ab+ac
add by exponent rule.
x⁵⁺²=x⁷
<u><em>= x⁷</em></u>
