find the x: | 4x-15 | = | 5x+6 |
Answer:
x=9
Step-by-step explanation:
You can take out the absolute value sign first and get 4x+15=5x+6
You can subtract 4x from both sides and get 15=x+6
Then you subtract 6 from both sides to get 9=x
the ratio is 4 : 15

A clothing
store offers a rewards program in which customers earn points by making purchases at the
store. Every item bought is worth 8 points, and customers earn 20 points when they sign up. Write an
equation for the function that gives the number of points based on the number of items bought. How
many points will a customer have after making 16 purchases?
Answer:
Equation for the function: y=8x+20
Step-by-step explanation:
8 represents points per item/rate of change
20 represents the y intercept or what the person gains in the beginning that doesn't change.
8(16)+20
128+20
=148
After making 16 purchases the person will have 148 points.

Suppose that 13 inches of wire costs 39 cents. At the same rate, how many inches of wire can be bought for 21 cents?
Answer:
63 cents
Step-by-step explanation:
Suppose that 13 inches of wire costs 39 cents. At the same rate, how many inches of wire can be bought for 21 cents?
0.39/13 = 0.03in
o.03 X 21 = 0.63
so 63 cents check
63/21 should equal 39/13
63/21 = 39/13
63 X 13 = 39 X21
21 X 3 X 13 = 3 X 13 X 21
yes
21 X 3 X 13 = 21 X 3 X 13

14. This year, a rancher counted 225 horses on
the range. This count is 22 fewer than last
year. How many horses did the rancher count
last year? Let h be the number of horses
counted last year. Solve h-22 = 225 to find
the number of horses counted last year.
Answer:
247 horses
Explanation:
Key Info: 225 horses this year and this is 22 horses fewer than last year
We know that fewer means it is subtraction, but since we don't know how many horses were there last year we do the opposite which is addition.
In this case the inverse or opposite equation is 225 + 22 = h.
After adding this up you should get 247 horses were there last year.
There are 247 horse counts last year.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
A rancher counted 225 horses on the range, which is 22 fewer than last
year.
let h be number of horses counted last year.
Then, the number of horses count
h - 22 = 225
add 22 on both side
h -22 + 22= 225 + 22
h = 247
Hence, there are 247 horse counts last year.

3) Anna is selling tickets to the school's gymnastics competition. On the first day, she sells 5 adult tickets and 6 child tickets for a total of $58.00. On the second day, she sells 8 adult tickets and 11 child tickets for a total of $97.00. Which system of linear equations can be used to determine the cost of each adult ticket (x) and each child ticket (y)?
A) 5x + 6y = 58 8x + 11y = 97
B) x + y = 155 x + y = 30 Eliminate
C) 5x − 6y = 58 8x − 11y = 97
D) x + y = 58 8x + 11y = 97

Answer:
y-30 = 3(x-1)
Step-by-step explanation:
Point-slope form of an equation is
y-y1 = m(x-x1) where (x1,y1 ) is a point and m is the slope
We know on day 1 they exercised 30 minutes (1,30) where x is the number of days and y is the minutes. The rate increased 3 minutes each day so m = 3
y-30 = 3(x-1)

Answer:
15
Step-by-step explanation:
We know according to the figure that 9^2+12^2 = z^2,
as a result, we know that z^2 = 225
and z = 15
Another method is to recognize that this figure is similar to a 3-4-5 triangle. According to the converse of the Hypotenuse-Leg theorem, we get that the third length of the triangle is 15
