Answer:
15
Step-by-step explanation:
25 - 2t
t = 5
25 - 2(5)
25 - 10
= 15
Answer:
15
Step-by-step explanation:
The equation with the value t substituted for 5 will look like 25 - (2)5
first you multiply 2 and 5 because pemdas.
The equation Is now 25-10
25-10 is 15
The answer is 15

find the value of x and show how
Answer:
x≈ 5.4
Step-by-step explanation:
180°-110°= 70°
70° is the measure of the angle represented by 11x+11
set the equation equal to 70°
11x+11= 70°
-11 on both sides
11x= 59
÷11 on both sides
x≈ 5.4
11(5.4)+11≈ 70.4 ≈70
30 miles to kilometres

Write an equation for the line that passes through (-8.5, 11) and (5, -2.5).
9514 1404 393
Answer:
y = -x + 5/2
Step-by-step explanation:
The 2-point form of the equation of a line can be useful.
y = (y2 -y1)/(x2 -x1)/(x -x1) +y1
y = (-2.5 -11)/(5 -(-8.5))/(x -(-8.5)) + 11
y = -13.5/13.5(x +8.5) +11 . . . . . . simplify a bit
y = -x +2.5 . . . . . write in slope-intercept form
6. Find the sum or difference

The zurn family ate at a restaurant that was having 15% discount on that day .Their meal costs 64.75,and they left a 20% tip .What is the total cost of the meal
Answer:
[tex]66.05[/tex]
Step-by-step explanation:
Cost of meal = [tex]64.75[/tex]
Cost of meal after discount of [tex]15\%[/tex]
[tex]64.75-64.75\times 0.15[/tex]
[tex]=64.75(1-0.15)[/tex]
[tex]=55.0375[/tex]
Cost of the meal after tip of [tex]20\%[/tex]
[tex]55.0375\times (1+0.2)[/tex]
[tex]=66.045\approx 66.05[/tex]
The total cost of the meal was [tex]66.05[/tex].

Answer:
the slope is: Positive
slope is: 1/5
y-intercept: -4
equation is: y = 1/5x - 4
Answer:
Slope: Postive
Slope: 5
Y-Intercept: -4
Equation: y = 5x - 4
Step-by-step explanation:
A positive slope rises left to right, a negative slope rises right to left.
The slope is [tex]\frac{rise}{run}[/tex].
The y-intercept is where the line meets the y-axis.
The equation is written in the form y = mx + b, where m is the slope and b is the y-intercept.

The perimeter of two similar polygons are in the ratio 1:25. If the length of one side is the smaller polygon is 3 centimeters what is the length of the corresponding side?
Answer:
75cm
Step-by-step explanation:
The perimeter of two similar polygons are in the ratio 1:25. If the length of one side is the smaller polygon is 3 centimeters what is the length of the corresponding side?
Ratio is given as:
Small : Large
1 : 25
Smaller polygon length = 3cm
Therefore, the length of the larger polygon = x
Hence we have the proportion:
1/25 = 3/x
Cross Multiply
x × 1 = 25 × 3
x = 75 cm
The length of the corresponding polygon = 75cm

Find the cost of 4.8 kilograms of potatoes at the price of $0.75 a
kilogram?
Answer: $3.60
Step-by-step explanation:
If you need 4.8 kilograms of potatoes and each kilograms costs $0.75, then we should multiply 0.75 by 4.8 to find the cost of 4.8 kilograms of potatoes.
4.8 x 0.75 = 3.6.
Therefore, the cost of 4.8 kilograms is $3.60 dollars. I hope this helps, and good luck!

Write the equation for "16 is equivalent to the product of 7 and a
number d”
Answer:
16 = 7 * d or 16 = 7d
Step-by-step explanation:
16 is equivalent to the product of 7 and a number d
Substitute mathematical signs for the words-
is equivalent means =
product means to multiply *
16 is equivalent to the product of 7 and a number d
16 = 7 * d Could also be written as 16 = 7d

Question 3. Find the distance between P(4,5) and the line with equation 8x + 5y = 20
Answer:
Step-by-step explanation:
8x+5y = 20
y = (-8/5)x + 4
slope of the line is -8/5.
slope of any perpendicular to the line is ⅝.
line of slope ⅝ that passes through P(4,5):
y-5 = ⅝(x-4)
y = ⅝x + 2.5
find intersection of lines
⅝x + 2.5 = (-8/5)x + 4
25x + 100 = -64x + 160
89x = 60
x = 60/89, y = 260/89
distance between (60/89, 260/89) and (4,5) = 3.92

3 A small photograph has a width of 4 cm and a length of 6 cm
Dean enlarges the small photograph
The enlarged photograph has a length of 21 cm
Work out the width of the enlarged photograph
Answer:
14 cm
Step-by-step explanation:
Given that the width is 4 cm and the length is 6cm. If after enlargement, the length becomes 21 cm, the multiplier or factor of enlargement x may be computed as
6 * x = 21
Divide both sides by 6
x = 21/6
= 7/2 = 3.5
Hence increasing the width by the same factor, the width of the enlarged photograph will be
= 3.5 * 4 cm
= 14 cm

On the windowsill is a plant that is 10 inches tall. It is growing 3 inches per
week. A second plant, which is 17 inches tall, is on the coffee table. It is
growing 2 inches per week. Eventually the two plants will be the same
height. How tall will the plants be? How many weeks will that take? *
Answer:18 days
Step-by-step explanation:
Here's a short table of heights:
day 0: height = 1
day 1: height = 1 + (1/2)(1) = 3/2
day 2: height = (3/2) + (1/3)(3/2) = 3/2 + 1/2 = 2
The pattern of heights is ...
(day, height) = (0, 1), (1, 1.5), (2, 2)
The plant is growing 1/2 its original height each day, so we can write the equation ...
h = 1 + d/2
We want to find the number of days (d) that result in a height of 10 (ten times the original height).
10 = 1 + d/2
9 = d/2 . . . . subtract 1
18 = d . . . . . multiply by 2
It took 18 days for the plant to grow to 10 times its original height.
Answer:
it would take 9 weeks for both of the plants to equally meet the same height which is 33 inches
