First set up the ratio 2/5 = 10/x where <em>x</em> is the number of girls.
Now, we can use cross-products to find the missing value.
So we have (2)(x) = (5)(10).
Simplifying, we have 2x = 50.
Dividing both sides by 2, we find that x = 25.
So there are 25 girls in the class if there are 10 boys.
Answer:
x = 8
Step-by-step explanation:
Step 1: Write equation
2(x + 5) = 26
Step 2: Solve for <em>x</em>
<u>Distribute 2:</u> 2x + 10 = 26
<u>Subtract 10 on both sides:</u> 2x = 16
<u>Divide both sides by 2:</u> x = 8

Answer:17cm 5 cm°Step-by-step explanation:
Answer:
A. x = 10°, m∠FGH = 24°
B. m∠HGI = 24°
C. m∠FGI = 48°
Step-by-step explanation:
A. Bisected angles are congruent:
3x - 6° = 4x - 16°
3x = 4x - 10°
4x - 3x = 10°
x = 10°
m∠FGH = 3(10°) - 6 = 30° - 6° = 24°
B. m∠HGI = 4x - 16°
4(10°) - 16° = 40° - 16° = 24°
(Theoretically, we didn't need to solve this, they are both congruent because it is a bisected angle.)
C. m∠FGI = m∠FGH + m∠HGI
m∠FGI = 24° + 24° = 48°
