Answer:
42
Step-by-step explanation:
ABC + CBD = ABD
3x+33 + 5x+13 = 70
Combine like terms
8x +46 = 70
Subtract 46 from each side
8x+46-46 = 70-46
8x = 24
Divide each side by 8
8x/8 = 24/8
x=3
We want to find ABC
ABC = 3x+33 = 3*3 +33 = 9+33 = 42
3y+13=2y+2
y+13=2 (subtracting 2y from both sides)
y=-11 (subtracting 13 from both sides)
Answer:
50% are boys
Step-by-step explanation:
Total number of kids: 18+15=33
Percent of boys: 15/33=0.4545 repeating
0.4545 rounded to tenth: 0.5
0.5 to percent: 50%
You have to multiply 4/5 with 6. 4/5 times 6 equals to 24/5. you can simplify that into 4 4/5.
