1. its 23, because if you were to substitute 5 for x, 7(5) = 35 and if you were to substitute -3 for y, 4(-3) = -12. Therefore, 35 + -12 = 23.
Answer:
2=x
Step-by-step explanation
1) distribute 1/4 to 8x and 16- is now 2x+4=4x
2) minus 2x on both sides to get 4=2x
3) divide both sides by 2
4) 2=x
The answer is 128 cause 8×4×4=128
D is also correct. if you need an explanation let me know
<span>There are 8 girls per 15 campers because 8 divided by 7 boys and 8 girls. The proportion is 8/15. If there are 195 campers, then you are looking for the number of girls, so 8/15 = x/195, where x is the number of girls.
Solve for x.
15x = 8(195)
1560 = 15x
x = 104
104 girls.
Number of boys = y,
195-104=y
y = 91</span>
