885 = 5(x + 19)
what is x?
Answer:
x = 158
Step-by-step explanation:
Given
885 = 5(x + 19) ← divide both sides by 5
177 = x + 19 ( subtract 19 from both sides )
158 = x
Answer: x=158
Step-by-step explanation:

Answer:
3.9x+0.8y
Step-by-step explanation:
4x−5.2y+6y+7.9x−8x
Combine −5.2y and 6y to get 0.8y.
4x+0.8y+7.9x−8x
Combine 4x and 7.9x to get 11.9x.
11.9x+0.8y−8x
Combine 11.9x and −8x to get 3.9x.
3.9x+0.8y
It can also be converted to fraction form:
[tex]\frac{4y}{5}+\frac{39x}{10} = 3.9x+0.8y[/tex]

(Inequalities) what do you have to do when multiplying or dividing by a negative number?
Answer:
When we multiply or divide by a negative to solve an inequality, it's the same as multiplying or dividing by a negative to solve a regular equation! Just remember to multiply or divide both sides by the same quantity, then simplify! Remember, when multiplying or dividing by a negative YOU MUST FLIP THE INEQUALITY SIGN.
Step-by-step explanation:
You are welcome.
And I hope this helps. :)
Answer:
Step-by-step explanation:
If you begin with an inequality and wish to solve for one of the variables, you must isolate that variable on the right side of a new inequality. Now supposing that that variable is negative in the given inequality, and that you must change that sign to positive. Generally you can either multiply every term in the given inequality by -1 or divide every term by -1. In both cases you must change the direction of the inequality sign.
Example: Given -3x > 2 + 5y, solve for x. To do this, multiply all three terms in the inequality by (-1/3), which yields x on the left and -2/3 - (5/3)y on the right. We must reverse the direction of the inequality sign, so the final answer is x < -2/3 - (5/3)y.

what are some expressions that are equivalent to 6(m+2+ m)
Answer:
12m + 12 is one equivalent expression
Step-by-step explanation:
This can be found by distributing the numbers as shown below:
6(m + 2 + m)
6m + 12 + 6m
12m + 12
Awnser:
The awnser would be 8m in total.
You could do 4(m +4 m) or 8(m+0 m) or 3(m +5 m)Can someone please help me with math
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 6 , then
y = 6x + c ← is the partial equation
To find c substitute (2, 19) into the partial equation
19 = 12 + c ⇒ c = 19 - 12 = 7
y = 6x + 7 → B
Answer:
B. y = 6x + 7
Step-by-step explanation:
Since the equation in slope: intercept form, y = mx + b, identify the slope of the line as the coefficient next to the variable x
y = 6x + 7, m = 6
Use the given slope and point to substitute into the point-slope formula
[tex]y - y1 = m (x-x1)[/tex]
Slope: intercept form:
y = 6x + 7
Point-slope form:
y - 19 = 6 (x - 2)

Answer:
x=11.2
Step-by-step explanation:
Set up a proportion:
x+11/36 = 37/60
Cross multiply:
1332=60(x+11)
Distribute:
1332=60x+660
Subtract 660 from 1332
672=60x
Divide:
x=11.2

Answer:
=13/3
Step-by-step explanation:
1. Distribute
3+2(4−6)=8+1
3+8−12=8+1
2. Combine like terms
3+8−12=8+1
11−12=8+1
3. Add 12 to both sides of the equation
11−12=8+1
11−12+12=8+1+12
4. Simplify
11=8+13
5. Subtract 8x from both sides of the equation
11=8+13
11−8=8+13−8
6. Simplify
3=13
7. Divide both sides of the equation by the same term
3=13
3x÷3=13÷3
8. Simplify
If you cancel terms that are in both the numerator and denominator you will get:
=13/3

A car is traveling at a steady speed. It travels 1 1/2 miles in 2 1/4 minutes. How far will it travel in 46 minuets? In 1 hour?
Answer:
30.667, in 1 hour = 40 miles
Step-by-step explanation:
Set up a proportion so 1.5 miles / 2.25 minutes.
So 1.5/2.25 = x/46
solve for x 1.5(46)/2.25 = x so x = 30.667
In one hour is 60 minutes so 1.5(60)/2.25 = x
