-7x=35
x=35/-7=-5
put the value of x into any of the equations
y=-3(-5)-5

Explain step by step how to do 10.25 x .15.
Answers
Answer:
1.5375
Step-by-step explanation:
Multiply without the decimal points, then put the decimal point in the final answer
1025 x 15 = 15375
....
10.25 has TWO decimal places
0.15 has TWO decimal places
Therefore, when you multiply with the decimal points (10.25 x 0.15), the answer should have FOUR total decimal places.
So the answer is 1.5375

* EX. How to calculate percentage of a number. Use the percentage formula: P% * X = Y
Convert the problem to an equation using the percentage formula: P% * X = Y.
P is 10%, X is 150, so the equation is 10% * 150 = Y.
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.*
You get 8.4ml
On his way to the library , Jeff runs two blocks and then walks three more blocks.Sketch a graph to show the distance Jeff travels compared to time.
Answers
Answer:
Since I can't take a picture, I am going to explain how to draw it.
Step-by-step explanation:
When sketching the graph you must note if jeff is going up the y-axis and along the x-axis. In this case, run means he goes up every minute. So when jeff runs he is going up and 2 minutes have gone by. And when he walks he is going up 3 more but slower so it would double the time. Time would be on the x-axis and blocks would be labeled on the y-axis.
Hope this helps. : )

Step-by-step explanation: i know this it's hard to explain
It will take 1 3/4 gallons to paint the whole fence.
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.
We need to find the expression of 3/4 divided by 1/8
3/4 x 8= 6
Therefore, The value of 7.89 divided by 2 is; 3.945
Now consider the gallons to paint the whole fence be x
1 1/4/x = 5/7
1.25/x = 5/7
then Cross multiply;
(5 × x) = (1.25 × 7)
5x = 8.75
x = 8.75/5
x = 1.75 = 1 3/4 gallons

Pls make brainliest I need 1 more to reach expert
Graph 1 represents 2 inches represents 60 miles.
What is Graph?The graph is simply a structured representation of the data. It aids in our comprehension of the data. The numerical information gathered through observation is referred to as data.
The Latin term datum, which means "something provided," is where the word data originated.
Following the creation of a research question, data is continuously gathered through observation. The information is subsequently arranged, condensed, categorized, and visually portrayed.
We have
2 inches = 60 miles
The above statement shows that when there is 2 units on x axis then 60 units on y- axis.
From the given graph the graph 1 shows that 2 units on x axis and 60 units on y- axis.
Graph 2, 2 units on x axis then 125 units on y- axis.
Graph 3, 2 units on x axis then 115 units on y- axis.
Graph 4, 2 units on x axis then 175 units on y- axis.

Step-by-step explanation:
1 4/6-5/6=?
1 4/6=10/6
10/6-5/6=5/6
Answer:
five sixths pound
Step-by-step explanation:
Kip bought [tex]1\frac{4}{6}[/tex] pounds of toffee. He gave [tex]\frac{5}{6}[/tex] of a pound to his friend. How much toffee does he have left?
The narrator is asking how much he has left after giving some toffee to his friend, that means we have to subtract.
[tex]1\frac{4}{6}[/tex] - [tex]\frac{5}{6}[/tex]
We already have an equal denominator so we can just subtract.
[tex]\frac{10}{6}-\frac{5}{6}[/tex] = [tex]\frac{5}{6}[/tex]
Kip has [tex]\frac{5}{6}[/tex] pounds left.

Answer:
1. The first problem is wrong, it should be 0.5(3(15) + 2(20)) because the parentheses make sure that every purchased item is being divided by 2 (multiplying by 0.5 is the same as dividing by 2)
2. The second problem is partially correct. The first two answers you have checked are correct, but the last one is wrong. The third answer should be 6 + 12 instead because that's just a simplified version of 2(3) + 6(2), meaning they are equal
3. I cannot read your answers in the "Why or Why Not" column in the third problem, but the answers you gave in the "Evaluate" and "Does It Work?" columns are all correct.

Step-by-step explanation:
if this is useful please make me brainliest
**Explanation:** Most of the time, people use percentages to express a fraction or a portion of a whole. In fact, percent literally means "per 100" or "out of 100." So when you see 25 percent, for example, you could read it as "25 out of 100" or "25 per 100 parts." But you can also have percentages that are greater than 100 percent – and when that happens, there's at least one complete whole, or a whole number, hidden in there somewhere.
