Answer: z=2
Step-by-step explanation:
2 x 2 = 4 + 3 = 7
Answer: Okay, the answer is z=2.
Step-by-step explanation: Step 1: Simplify the both sides of the equation: 2z+3=7.
Step. 2: Subtract 3 from the both sides: 2z+3−3=7–3.
Last but not least is step 3. Divide the both sides by 2: 2z/2=4/2. So you get z=2. I hoped my step-by-step explanation formula substitution is very helpful, please mark me as Brainliest, and have a happy holidays!!!!!!! :D

Which multiplication expression can be used to check this division problem: 2/5 divided by 4/15 = 3/2
O 2/5 times 4/15
O 3/2 times 4/15
O 3/2 times 15/4
O 5/2 times 15/4
Answer:
I'm pretty sure it's B
Step-by-step explanation:
Answer:
3/2 times 4/15
Step-by-step explanation:
In division, the quotient times the divisor equals the dividend. This multiplication can be used to check if the math was correct.
Here's an example:
6 / 3 = 2
6 is the dividend, 3 is the divisor, and 2 is the quotient.
2 times 3 is 6, which proves that the quotient times the divisor is the dividend , and it also means that the quotient was correct.
(This example was used because the numbers are nice and easy, so they are good examples for this kind of thing)

Decrease £14132.77 by 14.5%
Give your answer rounded to 2 DP
Answer:
£12083.52
Step-by-step explanation:
Given amount:
Amount = £14132.77
Percentage decrease = 14.5%
Solution:
To decrease the given amount by 14.5% implies multiply it by:
[tex]\frac{100-14.5}{100}[/tex] = 0.855
Now;
Decreased amount = £14132.77 x 0.855
Decreased amount = £12083.52

The perimeter of a flower garden with three sides is 46 feet. One side of the garden is 11 feet long. Another side of the garden is 13 feet long. What is the length of the third side? Enter your answer in the box. feet
Answer:
22ftStep-by-step explanation:
Step one:
given that the orientation of the garden is a triangular shape(it has three sides)
the perimeter is given as=46ft
one side y=11ft
the second side z= 13ft
let the third side be xft
Step two:
the expression for the perimeter = z+y+x
46=11+13+x
46=24+x
solve for x
x=46-24
x=22ft
Therefore the third side is 22ft long

Jim is baking chocolate chip muffins. He has a total of 7 1/3 cups of chocolate chips, if each batch of muffins uses 2/3 of a cup of chocolate chips, enter the most number of batches of muffins Jim can make?
Answer: 11 batches of muffins
Step-by-step explanation:
From the question, we are given the information that Jim is baking chocolate chip muffins and that he has a total of 7 1/3 cups of chocolate chips, and each batch of muffins uses 2/3 of a cup of chocolate chips.
The most number of batches of muffins that Jim can make will be gotten by dividing 7 1/3 by 2/3. This will be:
= 7 1/3 ÷ 2/3
= 22/3 ÷ 2/3
= 22/3 × 3/2
= 11
Jim can make 11 batches of muffins.

Suppose there is a 1.1 drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 60.5, what will be the temperature when the plane reaches an altitude of 11,000?
Answer:
48.4° CStep-by-step explanation:
Step one:
We are told that there is 1.1° drop in temperature for each 1000 ft climb.
since the given altitude is 11,000ft,
hence there =(11000/1000)*1.1
= 11*1.1
=12.1°C drops in temperature.
Therefore, given that the temperature on the ground is 60.5° C
The temperature above is 60.5-12.1=48.4° C
The plane reaches an altitude of 11,000 is 48.4° C

In a triathlon, Kailee swam for 1 hour, biked for 1.75 hours, and ran for 1 hour. Her average biking speed was 2 times her average running speed, and her average running speed was 8 times her average swimming speed. The total distance of the triathlon was 55.5 kilometers. Write an equation and solve it to find Kailee’s average swimming speed in kilometers per hour.
The problem tells you to make a sketch, a table, and equation but I only want an equation please. No answer either.
Answer:
Swimming speed, S = 1.50 km/hr
Step-by-step explanation:
Let Kailee's running speed be R
Let Kailee's biking speed be B
Let Kailee's swimming speed be S
Given the following data;
Time for swimming = 1 hour.
Time for biking = 1.75 hour.
Time for running = 1 hour.
Total distance = 55.5km
Translating the word problem into an algebraic equation, we have;
Biking speed = 2*8S = 16S
Running speed = 8S
We know that the distance covered by an object or body is given by the formula;
[tex] Distance = speed * time[/tex]
Now we would find the distance covered in each activity (biking, running and swimming).
For biking;
[tex] Distance, D_{1} = 1.75*16S [/tex]
Distance, [tex] D_{1} [/tex] = 28S
For running;
[tex] Distance, D_{2} = 1*8S[/tex]
Distance, [tex] D_{2} [/tex] = 8S
For swimming;
[tex] Distance, D_{3} = 1*S[/tex]
Distance, [tex] D_{3} [/tex] = S
The equation for the total distance covered in the triathlon is given by;
Total distance = sum of all distances covered
[tex] Total distance = D_{1} + D_{2} + D_{3} [/tex]
Substituting into the equation, we have;
[tex] 55.5 = 28S + 8S + S[/tex]
[tex] 55.5 = 37S[/tex]
[tex] S = \frac {55.5}{37} [/tex]
S = 1.50 km/hr
Therefore, Kailee’s average swimming speed is 1.50 kilometers per hour.

The following table shows the salary of 7 people in an office last year.
Name Income
Andy £13500
Bevan £27500
Cheryl £13750
Deva £79000
Elliott £19250
Frankie £27500
Grace £15000
a) Work out the mean income to 2 DP.
b) Deva was given a large bonus for 30 years service.
Excluding Deva's income, what was the mean income for the remaining 6 workers to 2 DP?
Answer:
a. Mean = £27928.57
b. Mean without Deva's income = £19416.67
Step-by-step explanation:
The mean is calculated by dividing the sum of values by number of values. Given 7 values will be used to calculate mean.
So,
Number of values = n = 7
Now,
[tex]Mean = \frac{Sum}{No.\ of\ values}\\=\frac{13500+27500+13750+79000+19250+27500+15000}{7}\\=\frac{195500}{7}\\=27928.5714..[/tex]
Rounding off to two decimal places
Mean income = £27928.57
Now we have to calculate mean without Deva's income so the number of values will be 6 and the sum will be:
[tex]Sum = 195500-79000 = 116500[/tex]
The mean without Deva's income is:
[tex]Mean = \frac{116500}{6} = 19416.6666..[/tex]
Rounding off to 2 DP
Mean = £19416.67
Hence,
a. Mean = £27928.57
b. Mean without Deva's income = £19416.67
