Answer:
Step-by-step explanation:
First divide 18/45, which equals 2/5
Then convert 2/5 to a decimal: 0.4
Multiply 0.4 by 100%, which equals 40%
Answer:
water + vinegar = 24 oz
W + V = 24
Also, we know V = 2 W add 2 parts of vinegar to 1 part water
2W + W = 24 oz
W = 8 oz
V = 16 oz amounts to add
Answer:
triangle X and Z are congruent
Step-by-step explanation:
Step-by-step explanation:
29x - 3 + 15x + 7 = 180° because these two angles are supplementary
if we add like terms
44x + 4 = 180
44x = 176 divide both sides by 44
x = 4
29x - 3 = 13y - 17 because alternate exterior angles has same measurement
since we found the value of x let's rewrite the equation
4 × 29 - 3 = 13y - 17
113 = 13y - 17
130 = 13y divide both sides by 13
10 = y
Answer:
Step-by-step explanation:
A hole is an input value that makes both numerator and denominator equal to zero.
<u>Let's factorize the numerator and denominator:</u>
- 3x² - 108 = 3(x² - 36) = 3(x + 6)(x - 6)
- x² + 2x - 24 = x² + 6x - 4x - 24 = x(x + 6) - 4(x + 6) = (x - 4)(x + 6)
<u>We have same factor of x + 6:</u>
- x + 6 = 0
- x = - 6 is a hole
