can you show your work for this 4m-5(3m+10)=126
Answer:
m=−16
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4m−5(3m+10)=126
4m+(−5)(3m)+(−5)(10)=126(Distribute)
4m+−15m+−50=126
(4m+−15m)+(−50)=126(Combine Like Terms)
−11m+−50=126
−11m−50=126
Step 2: Add 50 to both sides.
−11m−50+50=126+50
−11m=176
Step 3: Divide both sides by -11.
−11m /−11 = 176 /−11
m=−16

Which value is a perfect square? 12 24 49 63
Answer: 49 is a perfect square.
Step-by-step explanation: We say that 49 is a perfect square because it is the product of an integer multiplied by itself, 7×7. If we had a square with an area of 50, this wouldn't be a perfect square because no integer, multiplied by itself, will give a product of 50.

Mateo has been studying after school while preparing for a test retake. His work paid off ! His score on the retake was a 94. This was quite a difference from the grade on his first attempt which was a 68. What is the approximate percent of change between the two tests?
Answer:
28%
Step-by-step explanation:
We know that 100 percent is total. Mateo first scored 68/100, then a retake got his score up to 94/100.
First, subtract the two numbers
94 - 68 = 26
Put 26 over 94 to make this 26/94
Divide to get 0.28 (simplified and rounded)
So the increase was 28%
Answer:
increase of 28?
Step-by-step explanation:
Okay so, I believe it is 28, let me explain. First, work out the difference (decrease) between the two numbers you are comparing. Next, divide the decrease by the original number and multiply the answer by 100. If the answer is a negative number, this is a percentage increase.

A hobby shop sells small and large toy cars. A small toy car is $5.50, and a large toy car is $9. What is an equation that relates the cost, Cin dollars
with the number of small toy cars, S, and the number of large cars, L. purchased?
Answer:
C = 5.50S + 9L
.............
The equation that relates the cost, Cin dollars with the number of small toy cars, S, and the number of large cars, L is C = 5.50S + 9L.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
A hobby shop sells small and large toy cars. A small toy car is $5.50, and a large toy car is $9.
Let S be the number of a small toy car and L be the number of a large toy car.
The equation can be made:
Total cost:
C = 5.50S + 9L
Thus, the equation that relates the cost, Cin dollars with the number of small toy cars, S, and the number of large cars, L is C = 5.50S + 9L.

what is the value of f
Answer:
f = 22
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
140° is an exterior angle of the triangle, thus
4f + 1 + 51 = 140, that is
4f + 52 = 140 ( subtract 52 from both sides )
4f = 88 ( divide both sides by 4 )
f = 22
HELP 66 hundreds÷10 Choose 1 answer: (Choice A) A 66 \text { thousands}66 thousands66, start text, space, t, h, o, u, s, a, n, d, s, end text (Choice B) B 66 \text { ones}66 ones66, start text, space, o, n, e, s, end text (Choice C) C 66 \text { tens}66 tens
Answer:
66 tens
Step-by-step explanation:
Required
Solve 66 hundreds / 10
First, we need to express 66 hundreds as a number.
1 hundred = 100
66 hundreds = 66 * 1 hundred
So:
66 hundreds = 66 * 100
66 hundreds = 6600
66 hundreds / 10 would then be calculated as:
66 hundreds / 10 = 6600/10
66 hundreds / 10 = 660
660 can be represented as:
66 hundreds / 10 = 66 * 10
or
66 hundreds / 10 = 66 tens
Hence, option C answers the question

0.008 is smaller than 0.8
c) 29.678 or 92.678
29.678 is smaller than 92.678
3) Arrange in ascending order
a) 7.043 , 7.403 , 7.304 b) 47 .63 , 47.636 , 47.736
Ascending order means a sequence from the lowest value to the highest value.
SO, in ascending order, the arrangement is:
a) 7.043 , 7.304 , 7.403
b) 47.63 , 47.636 , 47.736
4) Arrange in descending order
a) 0.587 , 1.587 , 0.1587 b) 789.560 , 786 . 065 , 798 .65
Descending order means a sequence from the highest value to the lowest value.
SO, in descending order, the arrangement is:
a) 1.587 , 0.587 , 0.1587

5) Arun had Rs 965.27 in the bank. He withdrew Rs 209.98. What amount of money is left in the bank?
Given that:
Arun's capital = Rs 965.27 in bank
and he made a withdrawal of Rs 209.98.
The amount left in bank = Rs 965.27 - Rs 209.98
The amount left in bank = Rs 755.29
6) Sachin's weight was 52.8 kg before he became ill. In the first week, he lost 2.9 kg but in the second week, he gained 0.72kg. What was his total weight at the end of the second week?
Initial weight = 52.8 kg
After he became ill:
During the first week, he lost 2.9 kg
He gained 0.72 kg in the second week.
His total weight after the second week = (52.8 - 2.9 + 0.72) kg
His total weight after the second week = 50.62 kg
7) The height of Akash is 1.26m and that of Arjun is 1.3m , who is taller and by how much?
Given that:
The height of Akash = 1.26 m; &
The height of Arjun = 1.3 m.
The Arjun is taller than Akash and he is taller by :
1.3 m - 1.26 m = 0.04 m
Arjun is taller than Akash and he is taller by 0.04 m
Solve the equation: 25^2n+1=625
Answer:
The value of n is 1/2.
Step-by-step explanation:
[tex] {25}^{2n + 1} = 625[/tex]
[tex] log_{25}(625) = 2n + 1[/tex]
[tex]2 = 2n + 1[/tex]
[tex]2n = 1[/tex]
[tex]n = \frac{1}{2} [/tex]
The solution for the given equation is n=624/625.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation is 25²n+1=625.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, 625n+1=625
625n=624
n=624/625
Therefore, the solution for the given equation is n=624/625.
