What is the solution to the problem a-15=22
Answers
Answer:
a=37
Step-by-step explanation:
22+15=37
Answer: The solution is: " a = 37 " .
____________________________
Step-by-step explanation:
____________________________
Given the equation:
a − 15 = 22 ; Solve for "a" .
Add "15" to each side of the equation;
to isolate "a" on one side of the equation;
and to solve for "a" :
a − 15 + 15 = 22 + 15 ;
to get:

Ten times the difference of a number x and 8
Answers
Answer:
Expression will be 10(x - 6).
Step-by-step explanation:
Let the given number is x.
Difference of this number and 6 will be represented by
(x - 6)
Then ten times the difference of this number and 6 will be represented by
10(x - 6)
Therefore, the statement " ten times the difference of a number and six " will be represented by the expression 10(x - 6)
If ΔABC ≌ ΔRPQ , ∠A = 35˚, ∠C=75˚ , Find the measure of ∠Q. *
Answers
Explanation:
The order of ABC and RPQ is important so we can match up the angles like so
angle A = angle R .... first lettersangle B = angle P .... second lettersangle C = angle Q ... third lettersMeaning that angle Q = 75 since angle C is this measure.
Answer:
∠ Q = 75
Step-by-step explanation:
The reason,
As we can see that Triangle ABC is congruent to Triangle RPQ, so that means, ∠A =∠R , ∠B = ∠P , ∠C = ∠Q
And ∠C = 75° which means, ∠Q = 75°

Find the perimeter and area of the figure.
its a triangle with sides of 3m 5m and 4m
The perimeter of the figure is
meters.
The area of the figure is
square meters.
Answers
Answer:
P = 12m
A = 6m^2
Step-by-step explanation:
Perimeter is the sum of all the lengths of a shape. The lengths of the triangle are given as 3m, 4m, and 5m, so to find the perimeter we just need to add them all together. 3+4+5=12, so the perimeter of the triangle is 12m.
The area of a triangle is found by multiplying its height by its base and then dividing the result by 2. The height of the triangle is not given, but the side lengths (3,4 and 5) indicate that the triangle is a right triangle. This means we can use the middle length as the height and the shortest length as the base.
So, the height of the triangle is 4m, and the base is 3m, so to calculate the area:
(3x4)/2=12/2=6m^2.
The area of the triangle is 6m^2.
Hope this helped!

Which justifies Step 6 of his work? the addition property of equality the identity property of addition the multiplication property of equality the identity property of multiplication.
1/2x - 3 = 7
One-half x minus 3 equals 7.
Step 1: add 3 to both sides
1/2x - 3 + 3 = 7 + 3
One-half x minus 3 plus 3 equals 7 plus 3
Step 2:
1/2x + 0 = 10
One-half x plus 0 equals 10
Step 3: One-half x equals 10
1/2x = 10
Step 4: Multiply both sides by 2
1/2x * 2 = 10 * 2
2 (one-half) x equals 2 (10)
Step 5:
1x = 20
1 x equals 20
Step 6:
x = 20
x equals 20.
identity property of multiplication states that when 1 is multiplied to an equation, the result remains the same.

4b. How many years from now will the level of carbon monoxide be at 8 parts per million? Round to the nearest tenth.
Answers
Answer:
4A=5.1 per million 4B=3.8 years
Step-by-step explanation:
4A. A=0.2^2+.01t+5.1 the current level would be 5.1

When given a raw score, explain how to use the normal curve to compare that score to the population.
Answers
Assuming you know the mean (mu) and the standard deviation (sigma), you would use the raw score (x) to get the z score through this formula
z = (x-mu)/sigma
If you get a positive z value, then the raw score is above the mean. If z is negative, then the raw score is below the mean.
The absolute value of z tells us how far away from the mean we are in terms of standard deviation.
Eg: z = -3 leads to |z| = |-3| = 3, so we're 3 standard deviations below the mean.

an architect designs a rectangular flower garden such that the width is exactly two thirds of the length. if 230 feet of antique picket fencing are to be used to enclose the garden, find the dimensions of the garden.
Answers
Answer:
length = 69 ft. width = 46 ft.Step-by-step explanation:
perimeter (p) = 2L + 2W
where P = 230 ft.
W = 2/3L
plugin values into the formula:
230 = 2L + 2(2L/3)
230 = 2L + 4/3L
230 = 10/3L
L = 690/10
L = 69
W = 2/3L
W = (2/3) 69
W = 46
P = 2(69) + 2(46)
P = 230 ft.
therefore,
the dimensions of the rectangular garden:
length = 69 ft
width = 46 ft.
