Width=7ftLength=7(4)=28ftStep-by-step explanation:
The length of a rectangle is four times its width.
If the perimeter of the rectangle is 70 ft,
let the width =x
length =4width=4x
According to the question,
the perimeter of the rectangle is 70 ft
2(length+width)=perimeter 2(4x+x)=702(5x)=7010x=70x=70/10x=7Therefore:-
width =x=7ft
length =4x=4×7=28ft

find the difference of (k+3)-(3k-5)
Step-by-step explanation:
(k + 3) - (3k - 5) = k + 3 - 3k + 5 [expand the brack and simplify like terms]
= -2k + 8
5(x-3)=3x+5 (solve for x)
Answer:
5x-15=3x+5
5x-3x=5+15
2x=20

Step-by-step explanation:
Answer:
x = 10
Step-by-step explanation:
Hello!
Let's distribute the parenthesis
Solve:
5(x - 3) = 3x + 55(x) - 5(3) = 3x + 55x - 15 = 3x + 5Now, we can rearrange the variable so that x is on one side and the numbers are on the other.
5x - 15 = 3x + 55x - 15 - 3x = 3x + 5 - 3x2x - 15 = 52x - 15 + 15 = 5 + 152x = 20We can isolate x by dividing by the coefficient of x (2).
2x = 202x ÷ 2 = 20 ÷ 2x = 10The value of x is 10.

Collins has a part-time job as a dog walker. The table below shows the amount of money Collins earned for different numbers of hours of work:
Collins' Earnings from Dog Walking
Number of Hours Worked Money Earned (dollars)
5 30
6 36
8
66
Part A: What are the missing numbers in the table? Show your work. (4 points)
Part B: Collins also does part-time yard work. The ratio of the number of hours Collins works to the money he earns in dollars is 1:7. Create a table to show the money earned by Collins for 5, 6, and 8 hours of doing yard work. (3 points)
Part C: How many more dollars does Collins earn doing yard work for 5 hours than working as a dog walker for 5 hours? Show your work. (3 points)
((No website links please I'm giving 15 points))
Answer:
Step-by-step explanation:
Part A:
For Dog walking, he earns $30 for 5 hours of work.
He earns $36 for 6 hours of work.
$30/5 hours = $6/hour
$36/6 hours = $6/hour
He earns $6/hour dog walking.
For 8 hours, he earns 8 hours * $6/hour = $48
To earn $66, he works 66/6 = 11 hours.
5 30
6 36
8 48
11 66
Part B:
He earns $7/hour for yard work, so multiply the number of hours by 7 to find the money he earns.
Table for yard work
Hours Money
5 $35
6 $42
8 $56
Part C:
For 5 hours, he earns $35 for yard work and $30 as a dog walker.
$35 - $30 = $5
PLS HELP Which value makes the equation 20−3x=5 true?
12
0
6
5
Answer:
hope this helps :)
Step-by-step explanation:
20−3x=5
Subtract 20 from both sides.
20-3x-20=5-20
⇒-3x=-15
divide both sides by 3
⇒-3x/-3=-15/-3
⇒x=5
Answer:
[tex] \sf \: d) \: x = 5[/tex]
Step-by-step explanation:
Now we have to,
→ Find the required value of x.
The equation is,
→ 20 - 3x = 5
Then the value of x will be,
→ 20 - 3x = 5
→ -3x = 5 - 20
→ -3x = -15
→ 3x = 15
→ x = 15 ÷ 3
→ [ x = 5 ]
Hence, the value of x is 5.

It's a geometric sequence because the money is increasing by a percentage every year.
Please help with this math problem ASAP! I will give brainliest!
Part A
Refer to the diagram below. Specifically, refer to figure 1.
Point P is added to form a right triangle.
J is at (-7,2) and P is at (11,2). Segment JP is 18 units long.
We split segment JP into 4 equal pieces to get 18/4 = 4.5; this result is added onto the x coordinate of J to get -7+4.5 = -2.5 which is the x coordinate of point Q. So Q is at (-2.5, 2)
The value -2.5 is the x coordinate of point S as well.
Notice how the ratio JQ:QP is equal to 1:3.
----------
The distance from P to H is 6 units, which divided into four pieces means 6/4 = 1.5 is added onto the y coordinate of P to get 2+1.5 = 3.5; this is the y coordinate of points R and S as the diagram indicates. Like in the previous section, the ratio PR:RH is equal to 1:3
So ultimately point S is located at (-2.5, 3.5)
If we used the distance formula to compute the lengths of segments JS and SH, then we should find that they are in the ratio 1:3. In other words, segment SH is 3 times longer compared to segment JS. This would help confirm the answer. I'll let you do this confirmation part.
Answer: (-2.5, 3.5)============================================================
Part B
Refer to figure 2 this time.
We'll have a similar thing going on here as done in part A, though the points Q and R are in different locations.
To find where Q must be, we take 5/6 of the distance from J to P (which we found was 18 units). So (5/6)*18 = 15. This 15 is added onto the x coordinate of J to get -7+15 = 8. This is the x coordinate of point Q and point T.
Similarly, (5/6)*(length of segment PH) = (5/6)*6 = 5 is added onto the y coordinate of P to form the point R(11,7). The y coordinate of this helps form the y coordinate of the point T.
In short, point T is located at (8,7)
You should find that JS/SH is equal to 5/6 when you apply the distance formula to compute the lengths of JS and SH. I'll let you do this confirmation.

In Ms. Enderson's class there are 14 boys and 12 girls. What percent of girls are in the class?
Answer:
46.15%
Step-by-step explanation:
# of girls + # of boys = total # of students
12+14=26
# of girls / total # of students = percentage of girls in the class
12÷26=0.461538
Move the decimal place over two spots or multiply by 100 for the percent
46.1538%

Find the measure of each angle indicated
Answer:
67°
Step-by-step explanation:
1. The final angle in the top triangle is : 70
The angles in a triangle add up to 180° so 74 + 36 = 110 and 180 - 110 = 70
2. Vertically opposite angles are equal so the angle opposite the one we just found is 70° as well
3. The angles in a triangle add up to 180° so 70 + 43 = 113 and 180 - 110 = 67
Therefore, ? = 67°

f(-1) = 2
f(0) = 3
f(-5) = -40
Answer:
f(-1) = 2
f(0) = 3
Step-by-step explanation:
f(a) = 3a - a²
f(4)= 3*4-4²= -4 ⇒ correct
f(3)= 3*3-3²= 0 ⇒ correct
f(-1) = 3*(-1)-(-1)²=-3+1= -2 ⇒ incorrect
f(0) = 3*0-0²= 0 ⇒ incorrect
f(-5) = 3*(-5)-(-5)²= -15-25= -40 ⇒ correct
