Step-by-step explanation:
he can vacuum 3 cars in 17 minutes
so in 1 hour its (60/17) x 3
Or you can do 17/3 for how long it takes to clean 1 car
then divide 60 by that number, you round down for both since you don't complete the car if its a decimal

Is 2x+5=10 an example of an expression? Why or why not? If not, what would you call it instead?
Answer:
No; equation
Step-by-step explanation:
2x+5 = 10 is not an expression rather it's an equation because it has an equal sign. An expression is a number, a variable, or a combination of numbers and variables and operation symbols. An equation is made up of two expressions connected by an equal sign.

A. 4
B.7.5
C 5
D. 3
Step-by-step explanation:
your answer is C 5. also to find the answer by yourself get a ruler then measure the big one then the little one in mm. Then you can check how much larger they are then each other. In this case it is dilated to be twice the size. you call tell in this case by looking at the measurements it already gives you as you can see they both have the same labeled side, 3 and 6. 3 times 2 = 6 therefore it's twice the size

walks home when he is done eating. Explain, in your own words, how we can figure out how many miles he walked in total?
Answer:
14 miles
Step-by-step explanation:
Isaac is walking 14 miles because if it is seven miles to the store, he has to walk seven miles back. Seven plus seven is fourteen.

Triangle DEF is formed by connecting the midpoints of the sides of triangle ABC. The lengths of the sides of DEF are shown. What is the length of BC?
Answer:
may be it's helpful✌️..........
Applying the triangle midsegment theorem, the length of BC is: 8.
The Triangle Midsegment Theorem?Based on the triangle midsegment theorem, there are three midsegments in every triangle.The midsegments are parallel to each of their corresponding third sides.Length of midsegment = half of the length of the third side.Given:
DF = 4 (midsegment)
BC = ? (Third side).
Therefore,
BC = 2(DF)
BC = 2(4)
BC = 8
Therefore, applying the triangle midsegment theorem, the length of BC is: 8.

A number is divided by 2 and the result is added to 6. The new result is multiplied by 5, and then 16 is subtracted. The final result is 134. What is the number?
Answer:
48
Step-by-step explanation:
Do everything backwards
134 + 16 = 150
150 divided by 5 = 30
30 - 6 = 24
24 times 2 = 48
What is the equation of the line that passes through the point (7,2) and has a slope of 1
Answer:
y=x-5
Step-by-step explanation:
For this, use point-slope formula, which is (y-y1)=k(x-x1), in which k is slope.
Now, substitute in your values. (y-2)=1(x-7)
Then, since you got y-2=x-7, add 2 to both sides.
You get y=x-5
y = x +5 is the equation of the line that passes through the point (7,2) and has a slope of 1.
What is an equation of a line?The equation of a straight line is y=mx+c where m is the gradient and c is the height at which the line crosses the y -axis, also known as the y-intercept. There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form.
given, a line that passes through the point (7,2) and has a slope of 1
Since the Slope of the line = 1
From the slope-intercept form of the line
y = mx + c
thus, the Equation of the line
y = 1 * x + c
y = x + c
Since this line passes through coordinates (7, 2 ) this point will satisfy the equation
7 = 2 + c
c = 5
hence, the equation of a line
y = x +5
therefore, the equation of the line that passes through the point (7,2) and has a slope of 1 is y = x +5.

Select the correct answer.
The equation of a line is y=-3x - 2. What are the slope and the y-intercept of the line?
A. slope = -3 and y-intercept = 2
B. slope = 3 and y-intercept = -2
C. slope = 3 and y-intercept = 2
D. slope = -3 and y-intercept = -2
Answer: D
Step-by-step explanation:
The slope of a linear equation is the m value in the linear equation y=mx+b, in this case m=-3. The y-intercept is the b value in the linear equation y=mx+b, in this case b=-2.
A marching band stands in a triangle formation. The drum major stands at A, one of the vertices of the triangle. The whole formation marches 3 units left and 5 units up. They then march 2 units left and 2 units up. After the movement, what coordinates will the drum major be standing on? A. (11, 3) B. (11, 11) C. (1, 11) D. (1, 3)
Answer:
D. (1, 3)
Step-by-step explanation:
Based on the image uploaded, during the first march, move point A, 3 units left, the new position will (3, -4), then move point A again 5 units up, the new position will be (3,1).
From second march move point A 2 units left, the new position will be (1,1), finally move point A 2units up, the new position and last position will be (1, 3).
Thus, the drum major be standing on (1, 3)
