Answer:
The Answer is A I'm positive
Answer:
The answer is option AStep-by-step explanation:
[tex] \frac{2}{3} x - 1 = 4 \\ [/tex]
Move 1 to the other side of the equation
That's
[tex] \frac{2}{3} x = 4 + 1 \\ \frac{2}{3} x = 5[/tex]
Multiply through by 3 to eliminate the fraction
We have
[tex]3 \times \frac{2}{3} x = 5 \times 3 \\ 2x = 15[/tex]
Divide both sides by 2
[tex] \frac{2x}{2} = \frac{15}{2} \\ [/tex]
We have the final answer as

Aaron removes 29 candies from a jar. There were originally 79 candies in the jar. How many candies are left in the jar?
50
Step-by-step explanation:
you just subtract the 29 from 79
There are 50 candies left in the jar.
What is mean by Subtraction?
Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
There are 79 candies in the Jar.
Aaron remove 29 candies from the jar.
Now,
Total number of candies in the jar =n 79
And, Aaron remove 29 candies from the jar.
Thus, Left candies in the jar = 79 - 29
= 50
Therefore, There are 50 candies left in the jar.

In a right triangle, one leg (a) is 10 cm, and its hypotenuse (c) is 26 cm. Find b?
Answer:
[tex]\boxed {\tt b=24 \ centimeters}[/tex]
Step-by-step explanation:
This is a right triangle, so we can use Pythagorean Theorem.
[tex]a^2+b^2=c^2[/tex]
a and b are the legs, while c is the hypotenuse.
One leg is 10 centimeters. The hypotenuse is 26 centimeters. Therefore,
[tex]a= 10 \ cm \\c= 26 \ cm[/tex]
[tex](10 \ cm )^2+b^2=(26 \ cm)^2[/tex]
Solve the exponents.
(10 cm)²= 10 cm * 10 cm= 100 cm²[tex]100 \ cm^2+b^2=(26 \ cm)^2[/tex]
(26 cm)²= 26 cm * 26 cm= 676 cm²[tex]100 \ cm^2+b^2=676 \ cm^2[/tex]
Subtract 100 from both sides of the equation.
[tex]100 \ cm^2- 100 \ cm^2+b^2=676 \ cm^2- 100 \ cm^2[/tex]
[tex]b^2=676 \ cm^2 - 100 \ cm^2[/tex]
[tex]b^2= 576 \ cm^2[/tex]
Take the square root of both sides of the equation.
[tex]\sqrt{b^2} =\sqrt{576 \ cm^2}[/tex]
[tex]b=\sqrt{576 \ cm^2}[/tex]
[tex]b= 24 \ cm[/tex]
The other leg of the triangle is equal to 24 centimeters.

Answer:
24; 24
Step-by-step explanation:
if x = 24:
24 - 12 = 12. That is true and the second equation is the same so x = 24 and y = 24
Answer:
So its 24 and 24 because
Step-by-step explanation:
The answer for the first equation is that x=24 because 24-12=12 so (x-12) = 12 is 24
For the second equation y is also 24 because it's the same equation just rearranged so y-12=12 is 24

Lila's office had already recycled 3 kilograms this year before starting the new recycling plan, and the new plan will have the office recycling 2 kilograms of paper each week. Write an equation that shows the relationship between the weeks x and the paper recycled y. Write your answer as an equation with y first, followed by an equals sign.
Answer:
y = 2x + 3
Step-by-step explanation:
Based on the information provided we can use the values to write a proper algebraic equation like the following one ...
y = 2x + 3
The equation above states that the total number of paper that is recycled is equal to the 2 kilograms that are being recycled on a weekly basis plus the 3 kilograms that have already been recycled. This means that the value of y depends on the input given for the value of x which is the number of weeks that have passed.

Let q(t) = 29t and r(t) = t/29. Which method could be the first step in proving that q(t) and r(t) are inverse functions?
Replace the t in the expression for q(t) with t/29, and replace the t in the expression for r(t) with 29t.
Replace the 29t in the expression for q(t) with t, and replace the t/29 in the expression for r(t) with t.
Replace the t in the expression for q(t) with 29t, and replace the t in the expression for r(t) with t/29.
Replace the 29t in the expression for q(t) with t/29, and replace the t/29 in the expression for r(t) with 29t.
Answer:
Replace the t in the expression for q(t) with t/29, and replace the t in the expression for r(t) with 29t.
Step-by-step explanation:
Given q(t) = 29t and r(t) = t/29, to show that q(t) and r(t) are inverse of each other, we can simply find q(r(t) and r(q(t))
To find q(r(t):
q(r(t)) = q(t/29)
q(t/29) is gotten by replacing t in q(t) with t/29 as shown;
q(t/29) = 29(t/29)
q(t/29) = 29t/29
q(t/29) = t
Also for r(q(t)):
r(q(t)) = r(29t)
r(29t) is gotten by replacing t in r(t)/with 29t as shown;
r(29t) = 29t/29
r(29t) = t
Since r(q(t)) = q(r(t)) = t, this shows that they are inverses of each other.

Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

The ratio of boys to girls at the track meet is 2:3. If there were 54 girls, how many boys were there?
1. 36
2. 27
3. 18
Answer:
36
Step-by-step explanation:
If you divide 54 by 3 you get 18. Now we get the ratio of boys which is 2 and you multiply it by 18 as 1 ratio I'm this case is 18.
Once you multiply the two numbers, you get 36 boys.
Hope this helps! :)
Answer:
36 boys
Step-by-step explanation:
The 3 part of the ratio relates to 54 girls.
Divide the number of girls by 3 to find the value of one part of the ratio.
54 ÷ 3 = 18 ← value of 1 part of the ratio, thus
2 parts = 2 × 18 = 36 ← number of boys
