Answer:
X=9
Step-by-step explanation:
10x-30 = 7x-3
10x-7x = -3 + 30
3x = 27
x=9
Answer:
238
Step-by-step explanation:
Start with Raven's ants since hers is the one that everyone else's is based off of.
Raven = 208
Haley has half of that plus 76, so
Haley = (208/2) + 76
Haley = 180
If Haley's farm doubles in population, she would have 360 ants. That number is equal to Nate's number + 122. We have an equation of sorts there to solve for Nate's ants:
180(2) = N + 122 so
360 = N + 122 and
N = 238
Nate has 238 ants in his farm.
The slope is undefined because of the formula y2-y1/ x2-x1
in this case in (5,4) the 5 is x1 and the 4 is y1. in (5,8) the five is x2 and the 8 is y2. Pug the number in for the formula and you will see that it is D. undefined.
15/3 = x/7.
Use cross products and multiply 15*7= 105/3= 35.
He can wash 35 cars in 7 hours..
Hope this helps!
