: 1) If you were going to solve these, you would set them up like this.
s+p=19
7s+10p=121
among the choices, b is the only one that is equivalent to one of these equations
2) The problem looks a little confusing. If the price is per box then they easily make $275.
8b+9h=53
20*8b+30*9h=275
If it's per batch, the answer is B.
3. x^2+y^2=16
y=x+4
solve the first equation for y
y=√16-x^2
x+4=√16-x^2
(x+4)^2=16-x^2
x^2+8x+16=16-x^2
2x^2+8x=0
2x(x+4)=0
x=0 or x=-4

Answer:
70% of adults do not have allergies.
Step-by-step explanation:
It states that 35 out of 50 adults do not have allergies. If we turn this into a fraction (35/50), we can then multiply the denominator by 2 to make it 100. We would then also multiply the numerator by 2.
35 x 2 =70
70/100 = .7
.7 is just the decimal form of 70%
Answer:
A.
B.
Step-by-step explanation:
<u><em>The complete question is</em></u>
Three collinear points on the coordinate plane are R(x, y), S(x+8h, y+8k), and P(x+6h, y+6k).
<em>Part A: Determine the value of RP/SP</em>
<em>Part B: Determine the value of RP/RS</em>
we know that
the formula to calculate the distance between two points is equal to

we have

Part A.We have to find the value of 
step 1
Find the distance RP

substitute the values in the formula



step 2
Find the distance SP

substitute the values in the formula




step 3
<em>Find the ratio RP/SP</em>


Part B. We have to determine the value of 
step 1
Find the distance RS





step 2
<em>Find the ratio RP/RS</em>


4(x-1)=1/2(x-8)
First, distribute.
4x-4=1/2x-4
Subtract 1/2x from both sides.
7/2x-4=-4
Add 4 to both sides.
7/2x=0
Divide both sides by 7/2.
x=0
The answer is x=0.
Hope this helps :)
