Answer:
a=10
Step-by-step explanation:
11a-(4a-7)=77
11a-4a+7=77
7a+7=77
7a=70
a=10
Answer:
a=10
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
11a−(4a−7)=77
11a+−1(4a−7)=77(Distribute the Negative Sign)
11a+−1(4a)+(−1)(−7)=77
11a+−4a+7=77
(11a+−4a)+(7)=77(Combine Like Terms)
7a+7=77
Step 2: Subtract 7 from both sides.
7a+7−7=77−7
7a=70
Step 3: Divide both sides by 7.
[tex]\frac{7a} {7} = \frac{70} {7}[/tex]
Thus a = 10

Gabe has a great job. He earns money on an hourly basis and he was given a signing bonus to switch jobs. He forgot how much they said they would pay him by hour but on his time card he has at 4 hours he has earned 1,120 and at 10 hours he has earned 1,480. What is an equation that will model this situation? How much money will he earn in a 40 hour work week?
Answer:
Pay for 40 hours would be [tex]\geq 40 * 148[/tex]
Step-by-step explanation:
Gabe works for 4 hours and earns $ 1,120
Pay for one hour is [tex]\frac{1120}{4} = 280[/tex]
When he works for 10 hours, he earns $1480.
Pay for one hour is
[tex]\frac{1480}{10} = 148[/tex]
Thus the per hours pay must be greater than or equal to 148 dollars
Pay for 40 hours would be [tex]\geq 40 * 148[/tex]

The final answer is -16.875
Smo answer these and show work plz
Answer:
Step-by-step explanation:
1) multiply the three dimension
V = 7 x 2 x 4 = 56 cm^3
2) find the base area
base area = (9 x 3)/2 = 13,5 km^2
multiply the base area for the height
V = 13,5 x 5 = 67,5 km^3
3) find the trapezoid area
trapezoid area = [(base 1 + base 2) x h]/2 = [(4+6) x 1.7]/2 = 8.5 cm^2
mutiply the trapezoid area for the height that the priam would assume if the base will touch the ground
V = 8.5 x 4 = 34 cm^3
4) find the base area
base area = radius^2 x pi = 2^2 x pi = 12,57 yd^2
multiply the base area for the height
V= 12.57 x 6 = 75.40 yd^3
5) find the base area
base area = 9^2 x pi = 81 x pi = 254.47 ft^2
multiply the base area for the height
V = 254.47 x 5 = 1272.35 ft^3
6) multiply the three dimensions
V = 12 x 11 x 9 = 1188 yd^3
7) find the trapezoid area
trapezoid area = [(12+6) x 6.3]/2 = [20 x 6,3]/2 = 63 in^2
mutiply the trapezoid area for the height that the priam would assume if the base will touch the ground
V = 63 x 16 = 1008 in^3
8) find the base area
base area = (leg1 x leg 2)/2 = (4 x 3)/2 = 6 m^2
multiply the base area for the height
V = 6 x 9 = 54 m^3

hope this helps you out good luck with your math

answer for brainlest for 25 points
Answer:
1. 23/4 , 2. 5.555... , 3. 5 1/2 , 4. √28
you want to make them all into decimals so you can compare then easier
23/4 would be 5.75
√28 (just put it in a calculator) would be 5.29
5 1/2 would be 5.5 (make it into a improper fraction 11/2 then do 11/2 and you get 5.5)
and you have 5.555.
so...
5.75
5.29
5.5
5.55555
first is 5.75 it's bigger because of the .(75)
then 5.555 because it's .(55)
then 5.5 because it's .(50)
and the last one 5.(29)
(a) Anne, Barry and Colin share a prize in the ratio 3:4:5.
Colin gives 1/3 of his share to a charity.
What fraction of the whole prize does Colin give to the charity
Answer: 1/12
Step-by-step explanation:
1. Add up the 3 parts making 12
3:4:5 = 3+4+5=12
2. Out of the ratio we know that Colin gets 5 parts which is 5/12
3. If we subtract 5/12 from 1/3 we should get an answer of 1/12
5/12-1/3 =1/12
6^1-x=10^x how do I solve for x?
Answer:

Answer:
a=76 b=83
Step-by-step explanation:
for a. we divide 6688(area) by 88 to find the width bc 88*w=6688
6688/88 is 76 so a=76
Since 312 is perimeter we have to subtract 73 twice and then divide that by 2 bc 73+73+L+L=312
(312-73-73)/2=83 so b=83

About 150 million tons of plastic waste is in the world’s oceans. If each 001/B system can clean up 10,000 tons of plastic per year, how many systems would have to be deployed to meet the Ocean Cleanup’s goal of cleaning the oceans by 2040? Write a y = mx equation to solve.
Answer:
750 systems are needed in 20 years to clean 150 million tons wastes.
Step-by-step explanation:
Total waste = 150 million tons
Waste cleaned each year by 1 machine = 10,000 tons
No of years from 2020 to 2040 = 20 years
Waste cleaned in 20 years by 1 machine = 20* 10,000= 200,000 tons
Machines needed in 20 years to clean 150 million tons wastes using
y= mx ( where m= number of machines)
and x is the waste cleaned in 20 years by 1 machine
150,000,000 = m 200,000
or m = 150,000,000 /200,000
m= 750

The area of the triangle below is 25/12 square centimeters. What is the length of the
base? Express your answer as a fraction in simplest form.
5/3 cm is the height
Answer:
5/2 cm
Step-by-step explanation:
Given that:
Area of triangle = 25/12 cm
Height of triangle = 5/3 cm
Let,
Length of the base = b
Recall :
Area of a triangle = 1/2 * base * height
Substitute the values above into the equation :
25 /12 = 1/2 * b * 5/3
25 /12 = 5b/ 6
Using cross multiplication
25 * 6 = 12 * 5b
150 = 60b
Divide both sides by 60 to isolate b
150/60 = 60b / 60
b = 5/2 cm

AD and MN are chords that intersect at point B.
A circle is shown. Chords A D and M N intersect at point G. The length of A B is 9, the length of B D is x + 1, the length of M B is x minus 1, and the length of B N is 15.
What is the length of line segment MN?
Answer:
[tex]MN = 18[/tex]
Step-by-step explanation:
Given
[tex]AB = 9[/tex]
[tex]BD = x + 1[/tex]
[tex]MB = x - 1[/tex]
[tex]BN = 15[/tex]
See attachment
Required
Determine MN
The products of the segments of two chords that intersect are always, equal.
So, we have:
[tex]AB * BD = MB * BN[/tex]
[tex]9 * (x + 1) = (x - 1) * 15[/tex]
Open bracket
[tex]9x + 9 = 15x - 15[/tex]
Collect like terms
[tex]15x - 9x = 9 + 15[/tex]
[tex]6x = 24[/tex]
Solve for x
[tex]x = \frac{24}{6}[/tex]
[tex]x = 4[/tex]
The length of MN is calculated as:
[tex]MN = MB + BN[/tex]
[tex]MN = x - 1 + 15[/tex]
Substitute [tex]x = 4[/tex]
[tex]MN = 4 - 1 + 15[/tex]
[tex]MN = 18[/tex]
