evaluate
7n-(m+18)
if n = 4; m=10 how do you solve ?
Answer:
7(4) - (10+18)
28 - 28
0
Step-by-step explanation:
Step-by-step explanation:
okay, 7 (n) if n = 4 that means 7 times 4 so that equals 28 BUT we do (m + 18) first so if m= 10 that means (10 + 18) would be 28, so
28 - 28= 0
Find the distance between line OP the x's and y's are given please answer this with a fraction or decimal, I would appreciate it and give thanks to anyone who can help:)
Answer:
c ≈ 5.83095189485
Step-by-step explanation:
We can use the Pythagorean Theorem [tex](a^{2} +b^{2} =c^{2} )[/tex] for these kinds of problems.
So, pretend that line is the hypotenuse of a right triangle. One side would be
3 units long and another would be 5 units long. Let's plug that into the theorem.
3² + 5² = c²
Simplify.
9 + 25 = c²
Add.
34 = c²
And now square root both sides.
√34 = c
c ≈ 5.83095189485
When Sergio went to dinner with his brother, the bill was $51.19. What was the total they paid if they left a 15% tip?
Answer:
The total they paid was $58.8685
Step-by-step explanation:
Let us solve the question using the percentage method
∵ Sergio went to dinner with his brother
∵ The bill was $51.19
∵ They left a 15% tip
→ That means they pay extra money 15% of $51.19
∴ The total they paid = the bill + 15% of the bill
∵ 15% of the bill = 15% × 51.19
→ Change 15% to a decimal by divide it by 100
∴ 15% of the bill = [tex]\frac{15}{100}[/tex] × 51.19
∴ 15% of the bill = 0.15 × 51.19
∴ 15% of the bill = $7.6785
→ Substitute it in the total they paid
∵ The total they paid = 51.19 + 7.6785
∴ The total they paid = $58.8685
∴ The total they paid was $58.8685

solve 10x-10g(4x-2)=1
Answer:
Below
Step-by-step explanation:
x=[tex]\frac{1-20g}{10(1-4g)}[/tex]
Answer:
using BODMAS=(4x-2)=(2x)
10x-10g(2x)=
10x=10+(2x)=
10x=20x
divide both sides by 10
10x/10=20x/10
x=20/10
x=2

(-4,6), slope=-1
Write the slope-intercept equation using the given information.
Answer:
y = -x +2
Step-by-step explanation:
y = mx + b
y=6
x=-4
m=-1 (m is the slope)
b=? (b is the y-intercept)
Putting these numbers into this equation,
6 = -1(-4) + b
b=6-4
b=2
So the equation is y = -1x + 2
or just y = -x +2
A bear cub weighed 10 pounds. Each month it gains 5 pounds. Which equation correctly shows this linear relationship.
A.Y=5x +10
B.Y=10x +5
C.Y=5x-10
D.Y=10x-5
Answer:
A. Y = 5x + 10
Step-by-step explanation:
The bear gains 5 pounds a month. The X represents the months in which five pounds gradually build. This is represented by 5x. We need to add the bears original 10 pounds so Y = 5x + 10.

There are 90 calories in a 3/4 cup serving of cereal.
How many calories are in 1 cup?
How many calories are in 6 cups?
90
3/4
=1
=6
Answer:
120 calories in 1 cup, 720 in 6 cups
Step-by-step explanation:
I divided 90 by 3 to get 1/4 cup and then multiplied it by 4 to get for one cup. From there I multiplied by 6
Answer:
1 cup=120 calories 6 cups=720 calories
Step-by-step explanation:
We know that there are 90 calories in 3/4 of a cup and we can figure out that 30 calories are in each 1/4 of a cup because 90 divided by 3 equals 30 then just add 30 calories to 90 and get 120. Finally just do 120 times 6 and get 720 .
