Answer:
a = -7 and b = 1. The constant term is 4
Step-by-step explanation:
In standard form, this equation is -7x^2 + x + 4 = 0
The coefficients are a = -7 and b = 1. The constant term is 4.
Answer:
450 ounces
Step-by-step explanation:
We know that the cost of the mixture 
must be the cost of the everyday moisturizing lotion 
plus the cost of the self-tanning lotion 
, which means 
.
The cost of any substance will be the cost per ounce of the substance (c), multiplied by the number of ounces (n), which means C=nc, so we have from the previous formula that we have:
But we also know that the number of ounces of the mixture must be the sum of the number of ounces of the everyday moisturizing lotion with the number of ounces of the self-tanning lotion, so we have
We want to calculate the number of ounces of the self-tanning lotion (
), so we solve for that variable:
And substitute our values in this formula, to get:
Can you help me with math
Answer:
123
Step-by-step explanation:
A+C and E+G will equal 180 separately. Because the lines are parallel we can see that C is equal to G so we can exchange them. Next we have to fill in an equation by using the two equations given which would be 180=9x+15+5x-3 Now solve it
Add alike terms: 180= 14x+12
Subtract 12 to both sides to get operations alone: 168=14x
divide by 14 to get X alone which is 12=x
Now fill in x
9(12)+15= 123
