Answer: x=5
Explanation:
Rearrange the equation
42-x=37 is the same as 37+x=42
Isolate the variable x by subtracting 37 from both sides
37-37 cancels out and 42-37 is 5
X=5 is what you’re left with

if the cost of 1 pen is 15.75, find the cost of 7 pens
Answer:
110.25
Step-by-step explanation:
Cost of 1 pen = 15.75
Cost of 7 pens = 15.75 × 7 = 110.25
Answer:
$110.25
Step-by-step explanation:
1 pen = $15.75
7 pens x $15.75 = $110.25
(this pen is expensive t.f)
The people of Bridgetown wanted to build a bridge across a nearby river. Since they were poor swimmers, their master Trigonomos agreed to measure the width of the river without actually crossing it. Trigonomos spotted a tree across the river and marked the spot directly across from it. Then he walked to another point 151515 meters down the river and found that the angle between his side of the river and the line connecting him to the tree was 76^\circ76 ∘ 76, degrees. What is the width of the river?
Answer:
60.16 m
Step-by-step explanation:
Let w = width of river
Using trigonometry :
The width, w of the river is can be calculated thus :
Tan θ = opposite / Adjacent
Tan 76 = w / 15
4.0107809 = w / 15
w = 15 * 4.0107809
w = 60.1617 m
Hence, width of the river is 60.16 m

Tesfa is x years old. his father is 4 times as old as Tesfa. Her mother is 7 years younger than his father. If their three ages add up to 101 years, how old is Tesfa?
tesfa = x
dad = 4x
mom= 4x-1
x+4x+4x-1=101
9x+1=101
9x=100
100/9= 11.1
On a map drawn to scale, 5 cm represents 30 kilometers. If a line a the same map that connects 2 cities is 7 cm long, what is the distance between the 2 cities?
Answer:
42
Step-by-step explanation:
You can use proportions to solve this problem.
[tex]\frac{5cm}{30km}[/tex]=[tex]\frac{7cm}{xkm}[/tex]
Now just cross multiply.
5cm*Xkm=7cm*30km
you can simplify the cm and km since its multipying.
5x=210
x=42
In Kite KLMN, find the measure of
Answer:
M = K =
101°Step-by-step explanation:
M = K, because it's a kite.
Kite has 2 angles on the left and right, each with the same size,The kite also has different angles at the other angle points.(Addition of kite angles result in 360°)
Therefore
360 = 63 + 95 + 2M
2M = 360-63-95
2M = 202
M = 202÷2
M = K = 101°
The size of each angle M and angle K = 101 degrees.

A new taxi company, Littleton Cabs, just opened in town. A cab ride for m miles costs 8.5+2m dollars. Polly took a 14-mile cab ride to the airport. What price did Polly pay for her cab ride?
Answer:
$36.50
Step-by-step explanation:
To find the price she paid, plug in 14 as m and simplify:
8.5 + 2m
8.5 + 2(14)
8.5 + 28
= 36.5
So, Polly paid $36.50
a) − 5 ( 6 n + 6 ) ≤ 30
b) 8 v − 4 ( v − 8 ) > 8
Answer:
a) n ≥ -2
b) v > -6
Step-by-step explanation:
You did not state what you would like us to do with these. I will assume simplify.
a)
− 5 ( 6 n + 6 ) ≤ 30 first, distribute -5
-30 n + -30 ≤ 30 now, add 30 to both sides so we may isolate n our variable
-30 n ≤ 60 now, divide -30 on both sides so we may isolate n completely. When we do this, the sign changes direction
n ≥ -2
b)
8 v − 4 ( v − 8 ) > 8 first, distribute -4 (note: two negatives equal a positive)
8 v - 4v + 32 > 8 now, simplify
4v + 32 > 8 now, subtract 32 from both sides
4v > -24 now, divide both sides by 4 to isolate v
4v > -24
v > -6

The sum of the speeds of two trains is 723.1 miles per hour. If the speed of the first train is 10.9 mph faster than that of the second train, find the speeds of each.
What is the speed of the first train?
9514 1404 393
Answer:
367 miles per hour
Step-by-step explanation:
The speed of the faster train is half the total plus half the difference:
s1 = (723.1 +10.9)/2 = 367 . . . . miles per hour
_____
Check
The slower train is 367-10.9 = 356.1, and the total is 723.1 mph, as required.
_____
If you want an equation, you can let x represent the faster speed. Then the total is ...
x + (x -10.9) = 723.1
2x = 723.1 +10.9
x = (723.1 +10.9)/2 = 367

There is a bag filled with 3 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 reds?
Answer: The probability of getting two red marbles is P = 0.141
Step-by-step explanation:
We know that in the bag there are 3 blue marbles and 5 red marbles, then there is a total of 8 marbles in the bag.
The probability of taking at random a red marble is equal to the quotient between the number of red marbles and the total number of marbles, this is:
p = 3/8
Suppose we got a red marble:
Now we replace the red marble we took, so in the bag there are again 3 red marbles and 8 total marbles, then the probability of getting another red marble is again:
q = 3/8
The joint probability (this is, the probability of both events happening) is equal to the product of the individual probabilities, with gives us:
P = p*q = (3/8)*(3/8) = 9/64 = 0.141

Answer:
31.5
Step-by-step explanation:
First we want to find what side NP is equal to. To do that we divide 4 by 12
12/4=3 so side mp=3
next we want to find the scale factor of the rectangles. to do that we divide 4 from 9
9/4=2.25
next we want to find what side st is equal too
to do that we multiply 3 by 2.25
3x2.25=6.75
finally we want to find the perimeter and to do that we do 2(6.75)+2(9)
2(6.75)+2(9)=31.5 so the perimeter of rectangle RSTU is 31.5
hope this helps :)

Answer:
15x² - 3x - 7
Step-by-step explanation:
(12x² + 2x) - (-3x²+ 5x + 7)
First open the parentheses by applying the distributive property.
To do this, multiply each term you have inside (-3x⅔ + 5x + 7) by -1.
Thus, you would have the following:
12x² + 2x + 3x² - 5x - 7
Add like terms
12x² + 3x² + 2x - 5x - 7
15x² - 3x - 7

The set for a school play needs a replica of a historic building painted on a backdrop that is 20 feet long and 16 feet high. The actual building measures 320 feet long by 256 feet high. A stage crewmember writes (x, y) arrow right ( 1/20 x, 1/20y) to represent the dilation. Is the crewmember's calculation correct if the painted replica is to cover the entire backdrop? Complete the explanation.
Answer:
Stage crewmember's calculation is incorrect
Correct = 1/16x 1/16y
Step-by-step explanation:
Given that:
Dimension of backdrop : 20 feets long ; 16 feets high
Actual dimension of building : 320 feets long ; 256 feets high
The correct scale factor can be obtained thus :
Ratio of backdrop dimension to the actual dimension of building
Length : 20 / 320 = 1 /16
Height : 16 / 256 = 1/16
Hence, stage crewmember's calculation of (1/20x ; 1/20y) is incorrect.
