Answer :
no. of days used to repair 1250m of road = 5
no. of days used to repair 1m of road = 5/1250
no. of days used to repair 8000m of road (8*1000m ) = 5/1250*8000= 32 days
Evaluate 3x + 7 for x = 5.
Answer:
22
Step-by-step explanation:
If x = 5, then plug 5 in for x .
3(5) + 7
15 + 7 = 22
Answer:
22
Step-by-step explanation: 3x + 7
3*5 = 15
15+7=22

Answer:
The answer is 6.5 hours.
Step-by-step explanation:
If you multiply the hours need to work during that week days(6) and the hours worked during the weekend(3.5) you get 33.5 hours worked over all. then, you subtract 40(the hours wanted) and 33.5(the hours worked normally) and you get 6.5.
on a certain hot summer's day, people used the public swimming pool. The daily prices are 1.50 for children and 2.25 for adults. The receipts for admission totaled 1258.50 How many children and how many adults swam at the public pool that day?
Answer:
Step-by-step explanation:
How many people used the public pool altogether? There isn't enough info
Anyways,
You would write two equations and solve using substitution / elimination / graphing
one equation is:
1.5x + 2.25y = 1258.5
(x is children, y is adults)

Answer:
aproximately 23.5 I believe
Step-by-step explanation:
ok, so first you square 17, which is 289. then you square 29, which is 841. subtract 289 from that:
841-289=552
now take the square root of 552
aproximately 23.5 I believe
Answer: 23cm
Step-by-step explanation:
a² + b² = c²
x² + 17² = 29²
x² + 289 = 841
x² = 552
√x² = √552
x ≈ 23 cm

The length of Bryan’s garden is 4 meters longer than 3 times the width. The perimeter of his garden is 72 meters. What are the dimensions (l, w) of his garden?
Answer:
8 m = width
28 m = length
Step-by-step explanation:
Let w = width
3w + 4 = length
P = 2w + 2l
= 2w + 2(3w + 4) = 72
2w + 6w + 8 = 72
8w + 8 = 72
8w = 64
w = 8 m = width
3w + 4 = 24 + 4 = 28 m = length

The first side of a triangle is 4 inches longer then twice th second side the third side of a trianhle
Question:
The first side of a triangle is four inches longer than twice the
second side. The third side of the triangle is 5 inches shorter than
the sum of the other two sides. The perimeter is 72 inches. Find
the lengths of the three sides.
Answer:
The sides of the triangle are: 11.5, 27 and 33.5
Step-by-step explanation:
Let the first side be f, the second be s and the third be t.
So, we have:
[tex]f =4 + 2s[/tex]
[tex]t = f + s - 5[/tex]
[tex]Perimeter = 72[/tex]
Required
Determine the length of the three sides
Perimeter is calculated as:
[tex]Perimeter = f + t + s[/tex]
Substitute values for f and t
[tex]Perimeter = 4+2s + f+s-5 + s[/tex]
[tex]Perimeter = f+2s +s+s-5+4[/tex]
[tex]Perimeter = f+4s-1[/tex]
Substitute values for f and Perimeter
[tex]72 = 4+2s+4s-1[/tex]
[tex]72 = 2s+4s-1+4[/tex]
[tex]72 = 6s+3[/tex]
Collect Like Terms
[tex]6s = 72 -3[/tex]
[tex]6s = 69[/tex]
[tex]s= 11.5[/tex]
[tex]f =4 + 2s[/tex]
[tex]f = 4 + 2 *11.5[/tex]
[tex]f = 27[/tex]
[tex]t = f + s - 5[/tex]
[tex]t=27+11.5 - 5[/tex]
[tex]t=33.5[/tex]
The sides of the triangle are: 11.5, 27 and 33.5

Alex bought a present for his friend. The box, with its dimensions, is shown below.
If Alex has 60 square inches of wrapping paper, does he have enough paper to wrap the gift? (Assume that the shape of the wrapping paper doesn't matter.)
O yes because the gift has a surface area of 48 square inches
O no because the gift has a surface area of 96 square inches
O yes because the gift has a surface area of 32 square inches
O no because the gift has a surface area of 64 square inches
Answer:
yes because the gift has a surface area of 48 square inches
Step-by-step explanation:
Surface area formula:
A = 2(wl + hl + hw)
2 · (4 · 4 + 1 · 4 + 1 · 4) = 48

Q1Angles forming a linear pair are supplementary and sum to 180°
x + 8x = 180°9x = 180°x = 20°The smaller angle is 20°
Q2A(-2, 10) reflected over x-axis
Rule for such a reflection is:
(x, y) → (x, -y)Point A will map to:
(-2, 10) → (-2, -10)Correct option is D
Q3One point is at the origin and two other points are at the distance m horizontally and vertically from the origin
The last point will have same distance m from the point (m, 0) and (0, m) and this will be point:
(m, 0 + m) = (m, m)Which of the following relations are functions?^^
Answer:
its c because the x is not repeating so let's say x are people and y is the are the location. multiple x values can give the the same y but an x value can only give one y if x give more than one y value, or in other words repeats itself, then is not a function

Answer:
(B)
Step-by-step explanation:
x is on the left side of the < symbol, so the shaded portion of the line will be on the left side of the boundary dot.
The boundary dot is plotted at the constant, which is 1/2 = 2/4. That plot is shown in selection B.
_____
Additional comment
I like to write inequality solutions using the < or ≤ symbols because the relative positions of numbers and variables match their relative positions on the number line. In this problem, we have x < 1/2, so the shaded portion of the line is on the left of the boundary dot, just as x is on the left of 1/2 in the inequality.
