If 120% of a is equal to 80% of b, then what is the value of a+b in terms of a and b?

Answers

120% of a
80% of b

120% = 120/100 =1.2
80%= 80/100 = 0.8

1.2a=0.8b | ÷1.2
1a = 2/3 b

1.2a=0.8b | ÷0.8
1b=1.5a


(a+b) = ((2/3b)+ (1.5a)) =2/3b + 1.5a
*not 100% sure

Answer:

120/100 a = 80/100 b

12/10 a = 8/10 b

10 (12/10) a = 10 (8/10) b

12a= 8b

3a= 2b

a+b in terms of a

b = 3/2×a

a+ 3/2×a = 5/2×a

a+b in terms of b

a = 2/3×b

b + 2/3.b = 5/3×b

Mai started a new exercise program. On the second day, she walked 5 minutes more than on the first day. On the third day, she increased her walking time from day 2 by 20% and walked for 42 minutes. Mai drew a diagram to show her progress.

Answers

Answer:

d = 30 minutes.

day one is equal to 30 minutes

day two is equal to 35 minutes

day three is equal to 42 minutes

Explanation:

The first step is to figure out how much day 2 was worth in total.

Using the model, we can see that 5 of the boxes from day three is equal to day 2.

42/6=7.

One of the boxes equals 7 minutes.

Next we find what all 5 of them equal.

7*5=35.

Day two was worth 35 minutes in total.

The next step is to figure out what d equals. In order to do that, we need to solve the equation:

d + 5 = 35.

subtract 5 from both sides.

d = 30.

Now we know that day one/D is equal to 30 minutes.

Day one: 30 minutes

Day two: 35 minutes

Day three: 42 minutes.

Hope that this is what your looking for. Have a good day and good luck!

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, a system of equations in​ slope-intercept form y₁ = m₁x₁ + b₁ and

y₂ = m₂x₂ + b₂.

We can use both substitution and graphing depending on the numerical values of the variables.

If the solution involves integer numbers, graphing and substitution are the proper methods to utilize. Substitution would be more effective since an accurate solution may be reached if the solution involves values that are not integers. If the intersection point doesn't have integer values, it can be challenging to understand graphs, so using this approach to solve would be ineffective.

Answers

Answer:

To help Its sales, the company should focus on producing Large

T-shirts. Approximately 80% of T-shirts the company

makes should be medium and large T-shirts to match the market preference. If the total number of T-shirts sold in a month is 45,000, 3,300

of these will likely be size small.

Step-by-step explanation:

In the survey, Large t-shirts are most frequently bought so they should be the primary focus if the company is trying to make more money.

To find the percentage of shirts that the medium and large shirts make up, first you find the total amount of shirts (11+37+83+19=150), then you will find how many mediuma and large shirts (37+83=120). Percentage is (120/150)*100=80%

To find the number of small shirts you can set up a proportion.

[tex]\frac{11}{150} =\frac{x}{45,000}[/tex], then cross multiply

150x=11*45,000

150x=495,000

x=3,300

2z = -12

Divide each side by 2

z = -6

So, the answer is z = -6
