what is the answer for combine y and 7
Answer:
7y
Step-by-step explanation:
The answer for combine y and 7 are 7a, 7 +y, 7 - y and 7/y.
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now the given statement is,
combine y and 7
Now a variable is a symbol (usually a letter) that stands for a value that may vary.
Here y is our variable.
When we combine numbers and variables in a valid way, using operations such as addition, subtraction, multiplication, division, exponentiation, and other operations and functions, the resulting combination of mathematical symbols is called a mathematical expression.
Thus, combining y and 7 may have result as-
7a, 7 +y, 7 - y and 7/y.
Thus, the answer for combine y and 7 are 7a, 7 +y, 7 - y and 7/y.

A down arrow is drawn with its tip at (2, 0). Then it undergoes a translation described bythe directed line segment (−3, 1). What direction is the arrow pointing?
Answer:
down
Step-by-step explanation:
In mathematics a when dealing with graphs a translation is basically just moving points left/right and up/down but it does not change the shape of the original figure in any way just moves its position. In this scenario, the down arrow's tip will be moved from point (2,0) to (-3,1) but the arrow will still be the same size and still be pointing downward.
Daniel rollerbladed 3 miles in 12 minutes. At this rate, how many miles will he rollerblade in 1 hour? Show your work.
Answer:
Daniel is rollerblading at 15 miles per hour
Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15
Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15

At the beginning of 2010, City A had a population of 2,425 and was growing by 27 residents per year. City B had a population of 1,813 and was growing by 63 residents per year. If this trend continues in what year will the populations of the two cities be the same?
Answer: 17 years
Step-by-step explanation:
City A is currently 2,425 people in number and growing at 27 per year.
An expression to find the population in a given year assuming the year is x would be:
= 2,425 + 27 * x
= 2,425 + 27x
Applying the same logic to City B would give an expression of:
= 1,813 + 63x
Equating these together will give the year they will be the same:
2,425 + 27x = 1,813 + 63x
2,425 - 1,813 = 63x - 27x
612 = 36x
x = 612/36
x = 17 years

- remember that the midline is always half of the sum of the other two legs.
here,
UX is the midline,
ST is the leg,
VW is the other leg.
so,
ST + VW = 2UX
now plug in,
25 + VW = 2(35)
25 + VW = 70
VW = 45

LaTeX: \Delta QRS\cong\Delta TUV,\:QS=3v+2,Δ Q R S ≅ Δ T U V , Q S = 3 v + 2 , and LaTeX: TV=7v-6,T V = 7 v − 6 , enter the lengths of QS
Answer:
The length of QS = 8
Step-by-step explanation:
From the above question:
Δ Q R S ≅ Δ T U V
Q S = 3 v + 2 , and T V = 7 v − 6 , enter the lengths of QS
Hence:
Step 1
We solve for v
QS = TV
3v + 2 = 7v - 6
Collect like ters
2 + 6 = 7v - 3v
8 = 4v
v = 8/4
v = 2
Step 2
Solving for Q S
Q S = 3 v + 2
v = 2
QS = 3(2) + 2
QS = 6 + 2
QS = 8
The length of QS = 8

If –3(y - 1) = 9, find the value of 1/2y
Answer:
The value of [tex]\frac{1}{2}y[/tex] is -1
Step-by-step explanation:
Equations
We have the equation:
[tex]-3(y - 1) = 9[/tex]
It's required to find
[tex]\frac{1}{2}y[/tex]
Let's solve the equation. Dividing by -3:
[tex]y - 1 = \frac{9}{-3}= -3[/tex]
Adding 1:
[tex]y=-3+1=-2[/tex]
Since y=-2, then y/2=-1
The value of [tex]\frac{1}{2}y[/tex] is -1

Option (3)
Step-by-step explanation:
Let the unknown angle of the triangle measure x°.
By applying cosine rule in the right triangle,
cos(x) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
cos(x) = [tex]\frac{33}{65}[/tex]
x = [tex]\text{cos}^{-1}(\frac{33}{65})[/tex]
x = 59.49°
≈ 60°
Therefore, option (3) will be the correct option.

before he can buy his new gaming system?
John need to save 2 dollars for 96 days
Answer:
96 days

Step-by-step explanation:
the sum of two numbers is 40.if the greater number is 8 more than the smaller one , find the numbers
Answer:
16
Step-by-step explanation:
let the smaller no be x so the greater no is 8 + x
soln
8+x + x = 40
8 + 2x = 40
2x = 40-8
2x = 32
x = 32÷2
therefore x = 16
Answer:
16 and 24
Step-by-step explanation:
let the 2 numbers be x and y, x > y , then
x + y = 40 → (1)
x = y + 8 → (2) [ greater number 8 more than smaller ]
Substitute x = y + 8 into (1)
y + 8 + y = 40, that is
2y + 8 = 40 ( subtract 8 from both sides )
2y = 32 ( divide both sides by 2 )
y = 16
Substitute y = 16 into (2)
x = 16 + 8 = 24
The 2 numbers are 16 and 24
The measure of the angles of a triangle are in the extended ratio of 3 : 7 : 10. Find the measures of the angles.
A. 27 degrees, 63 degrees, 90 degrees
B. 30 degrees, 60 degrees, 90 degrees
C. 30 degrees, 70 degrees, 100 degrees
D.33 degrees, 77 degrees, 80 degrees
Answer:
A. 27 degrees, 63 degrees, 90 degrees.
Step-by-step explanation:
Let the angle of the triangle be x
Given the following data;
3 : 7 : 10 = 3x : 7x : 10x
We know that the sum of the sides of a triangle is equal to 180 degrees.
3x + 7x + 10x = 180
20x = 180
x = 180/20
x = 9
For the first side;
3x = 3 × 9 = 27°
For the second side;
7x = 7 × 9 = 63°
For the third side;
10x = 10 × 9 = 90°
Therefore, the ratio of the angles of the triangle is 27° : 63° : 90°.
Answer:
The measure of the angles of a triangle are in the extended ratio of 3 : 7 : 10. Find the measures of the angles.
A. 27 degrees, 63 degrees, 90 degrees✓
B. 30 degrees, 60 degrees, 90 degrees
C. 30 degrees, 70 degrees, 100 degrees
D.33 degrees, 77 degrees, 80 degrees
A. is the right answer.Step-by-step explanation:
Let the required angles of the triangle be 3x, 7x and 10x
According to the above problem,
[tex]3x + 7x + 10x = 180 \\ 20x = 180 \\ x = \frac{180}{20} \\ \boxed{x = 9}[/tex]
Therefore the angles are :---
[tex]3x = 3 \times 9 = 27°✓ \\ 7x = 7 \times 9 = 63°✓ \\ 10x = 10 \times 9 = 90°✓[/tex]
