Answer:
x=9.5, y=5.75
Step-by-step explanation:
2x-5=14, 3x+2y=40
focus on 2x-5=14 first:
2x-5=14 (add 5 to both sides) 2x=19(divide both sides by 2) x=9.5
Now subtitute x into the second equation and find y:
3(9.5)+2y=40(simplify) 28.5+2y=40(subtract 28.5 on both sides) 2y=11.5(divide both sides by 2) y=5.75

1 What is an appropriate "2nd step" when solving the equation below? 2/3x - 8= 12 Add 8 to each side. Divide both sides by 3. Multiply both sides by 2. Multiply both sides by 3/2.
Answer:
multiply both sides by [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given
[tex]\frac{2}{3}[/tex] x - 8 = 12
first step
Add 8 to both sides
[tex]\frac{2}{3}[/tex] x = 20
second step
Multiply both sides by [tex]\frac{3}{2}[/tex] to clear the fraction
x = [tex]\frac{3}{2}[/tex] × 20 = 30
16.6 repeating as a fraction
Answer:
1/6
I apologize if it is wrong.
The repeating decimal 16.666... as a fraction is 50/3.
We have,
Consider
x = 16.6666... ______(1)
Multiply 10 on both sides.
10x = 10 x 16.6666...
10x = 166.666..... ______(2)
Subtract (1) from (2).
10x - x = 166.666..... - 16.666...
9x = 150
x = 150/9
x = 50/3
Thus,
The repeating decimal as a fraction is 50/3.

What is the value of m
Answer:
m = 10
Step-by-step explanation:
From the image given, we can tell that there are two sides for angle H for the segment IJ. From that we can see that angle H is a supplementary angle. A supplementary angle is an angle whose sum is 180°So: (2m+10)°+(5m+100)° = 180°(7m+110)° = 180°(7m)° = 70m = 10If a numser has an even exponent can it ever be negative when it is simplified?
Explain.
Answer: No, it can never be negative.
==================================================
Explanation:
Consider the expression x^2
If x were some negative number, say x = -3, then
x^2 = (-3)^2 = 9 which is a positive result.
Picking any negative number for x will make x^2 positive.
We can think of it like this
(-3)^2 = (-3)*(-3) = 9
The two negatives multiply to a positive.
This also happens with exponents 4,6,8, etc. Any even exponent will have an even number of negative signs, all of which cancel out.

which diagram show lines that must be parallel lines cut by a transversal
Answer: hope i helped with this answer~
Step-by-step explanation:
The fourth diagram show lines that must be parallel lines cut by a transversal
What is Straight line?A line is an infinitely long object with no width, depth, or curvature.
Parallel lines refers to two lines which can be found on the same plane, at an equidistance and does not meet.
A transversal is defined as a line that passes through two lines in the same plane at two distinct points in the geometry.
The fourth diagram has two same-side interior angles that are supplementary (add to 180°).
The converse of the same-side interior angle theorem states that if two lines are cut by a transversal and the same side interior angles are supplementary, then the lines are parallel.
Hence, the fourth diagram show lines that must be parallel lines cut by a transversal

If we decrease the time it takes for a car to travel over the same distance, this will (2 points) increase the speed have no effect on velocity or speed decrease the speed decrease the velocity
Answer:
Increase the speed
Step-by-step explanation:
The only way to decrease the time it would take to travel over a distance would be to increase the speed.
Answer:
see below
Step-by-step explanation:
if time decreases.... the velocity will decrease.
ex.
d = v/t
100 m = v/10 sec v = 1000 m/s
100 m = v/5 sec v = 500 m/s
100 m = v/1 sec v = 100 m/s
therefore,
if we decrease the time it takes for a car to travel over the same distance,
the velocity decreases too.

The Hartman family is saving $400 monthly for Ronald's college education. The family anticipates they will need to
contribute $20,000 toward his first year of college, which is in 4 years. Which best explains whether the family will
have enough money in 4 years?
The family will not have enough money. They will have saved only $16,000.
O The family will not have enough money. They will have saved only $19,200.
The family will likely have enough money. They will have saved $16,000 and have accumulated interest.
O The family will likely have enough money. They will have saved $19,200 and have accumulated interest.
Answer:
The family will not have enough money. They will have saved only 19,200
Step-by-step explanation:
The family will not have enough money. They will have saved only $19,200 is the best statement.
What is interest?
" Interest is defined as the amount of money which one has to pay while borrowing and charged while lending money."
According to the question,
Amount saved per month by Hartman family = $400
Amount need to pay fees after 4 years = $20,000
Total amount saved in 4years = 400 × 12 ×4
= $19200
Difference in amount needed = 20,000 - 19,200
= $800
Here it is not given that Hartman family has saved money in any bank.
Neither rate of interest is mentioned.
Hence, we conclude that the family will not have enough money. They will have saved only $19,200 is the best statement.

Answer:
210 divided 2 1/2= 84....
The 210 divided by 2 1/2 is 84.
To calculate 210 divided by 2 1/2, first, we need to convert the mixed number 2 1/2 to an improper fraction. The improper fraction for 2 1/2 is (2 * 2 + 1) / 2 = 5/2.
Now, we can perform the division:
210 ÷ 5/2
To divide by a fraction, we multiply by its reciprocal:
210 * 2/5
Now, perform the multiplication:
(210 * 2) / 5 = 420 / 5
Next, simplify the fraction by dividing the numerator and denominator by their greatest common divisor (GCD), which is 5:
420 ÷ 5 = 84
The result of 210 divided by 2 1/2 is 84. So, 210 ÷ 2 1/2 = 84.
