x-intercept: 7/30
y-intercept: −3
Step-by-step explanation:
Answer:
Step-by-step explanation:
For x-intercept:
Substitute y=0:
7x-10(0)=30
7x=30
x=30/7
For y-intercept:
Substitute x=0:
7(0)-10y=30
-10y=30
y=-30/10
y=-3

Help me this is due today!!!!!!!!
Mr. Dyer left a $12.60 tip at a restaurant. This represented 18% of his family’s dinner bill. What was the amount of the family’s dinner bill?
Answer:
$70
Step-by-step explanation:
$12.60 / .18 = $70
I hope this is right, but I am thinking it is since you have to multiply by .18 to get the tip value.

Latoya's softball team won 75%, or 18, of its game. Define a variable. Write and solve an equations to determine the number of games the team played.
Will give brainliest
Answer:
18 / 3 * 4 = a
a = 24
Step-by-step explanation:
so we know that 18 is = to %75 but we need to know what %100 is, to figure this out lets find a common denominator
so we know that %75 of something is 3/4, and to double check, we can take the fraction 3/4 and divide it the way its written, bc thats what a fraction is, a small division problem
3 / 4 = 0.75 or 75/100 or %75
so now we know we have 3 out of 4 parts of something, to find out how big each part is, we divide the number (18) by how many pieces we have...
18 / 3 = 6
so each 1/4 is = to 6, now to figure out the whole, we multiply by how many pieces are in said whole, in this case by 4
6 * 4 = 24
so since we know that 6 is = to %25 and we multiplied 6 by 4, we can do the same to %25...
25 * 4 = 100
and have the whole
this is basically a detailed explanation of the other answer
hope this helps :)
I need help with this. Mostly just 2a and 2b.
2a. A(t) = π(70 + 6t)^2 (Let t = 2 hours)
A(2) = π(70 + 6(2))^2 = 6724π
Now let t = 0 hours (result from part 1)
A(t) = π(70 + 6(0))^2 = 4900π
Average rate = 6724π - 4900π/2-0 = 912π
912π area covered per hour
2b. Let t = 1/2 hours, A(t) = π(70 + 6(1/2))^2 = 5329π,
Let t = 0 hours - result from last time was 4900π,
Average rate = 5329π - 4900π/1/2 - 0 = 858π
858π area covered per hour
Marcy goal was to collect 10 cans of food for a local food bank. She collected 160 cans use the grid to model to understand how to write this as a ratio, a fraction
Answer:
We're told that Marcy collected 160 out of 10 cans. That could be expressed as 160/10, but given that the numerator and denominator are both divisible by 10, we can factor that out and express it as 16/1. You can also express it as ratio of 16:1 cans collected to cans intended.
Answer:
As a ratio, this is expressed as
✔ 160 to 100
As a fraction, this is expressed as
✔ 160/100
As a percent, this is expressed as
✔ 160%

Which equation is the inverse of y = x^2– 36?
ОО
y=1/x+6
y=+ X+36
y=+ x +36
y=+Vx2+36
Answer:
y inverse = √(x + 36)
Step-by-step explanation:
inverse of y = x² - 36
=> x² = y + 36
=> x = √(y + 36)
interchange x and y
=> y = √(x + 36)

what is the best estimate for the sum of fractions 5//6 and 5/8
Answer:
The answer is 25/24 or 1.041
Step-by-step explanation:
Given 5/6 and 5/8, you can't find the sum at that point. This means we will have to find a common denominator, which will be 24.
6 x 4 = 24 and 8 x 3 = 24
Doing this, you will have to multiply the numerator and denominator by the value the denominator needs to be multiplied by to get 24.
5/6 x 4/4 = 20/24 and 5/8 x 3/3 = 15/24
After getting these values, you can then add them.
20/24 + 15/24 = 25/24 or 1.041
The best estimate for the sum of fractions 5//6 and 5/8 is 35/24.
We have to determine
What is the best estimate for the sum of fractions 5//6 and 5/8?
Sum of fraction;The addition of Fractions depends on one main factor which is the denominator of the fraction to be added.
There are different ways to add them depending on whether the denominators of the fractions to be added are like or unlike.
The sum of the fraction 5//6 and 5/8 is;
[tex]\rm= \dfrac{5}{6}+\dfrac{5}{8}\\\\=\dfrac{5\times 8+5\times 6}{48}\\\\= \dfrac{40+30}{48}\\\\=\dfrac{70}{48}\\\\=\dfrac{35}{24}[/tex]
Hence, the best estimate for the sum of fractions 5//6 and 5/8 is 35/24.
