Answer:

(4, 5)

Step-by-step explanation:

5x + y = 25

-3x + 2y = -2

5x + y = 25

y = 25 - 5x

-3x + 2 * (25 - 5x) = -2

-3x + 50 - 10x = -2

-13x = -52

x = 4

5 * 4 + y = 25

20 + y = 25

y = 5

Solution: (4, 5)

(4,5)
x=4
y=5

Add equation as + and - = -

2/3 a - 1/6 = 1/3

answer this math question asap pls

Answers

Answer:

a=3/4

Step-by-step explanation:

1. Get 2/3a by itself.

•Turn 1/3 to 2/6 by multiplying 1/3 by 2/2.

•Because you only add and subtract like denominators

This will make it look like:

2/3a - 1/6 = 2/6

Then, add 1/6 to both sides to get 2/3a by itself.

It'll look like this:

2/3a = 3/6

2. Get a by itself.

•Multiply the reciprocal (opposite) of 2/3 to get a alone.

This will look like:

(3/2) • 2/3a = (3/2) • 3/6

a = 18/24

3. Simplify.

Find the largest number that can simplify the equation.

For example, 18 ÷ 3 = 6, and 24 ÷ 3 = 8.

But the largest number you can divide both sides by is 6.

18 ÷ 6 = 3 and 24 ÷ 6 = 4.

3/4.

the answer is a= 3/4

Answer:

x = 1.2

Step-by-step explanation:

Essentially, because ABCDE and JKLMN are similar, their corresponding sides have a common ratio. To find x, we can simply the ratio between NJ and its corresponding side equal to the ratio of another pair of corresponding sides.

[tex]\frac{BA}{KJ}=\frac{AE}{JN}[/tex]

[tex]\frac{3}{1.8}=\frac{2}{x}[/tex]

3x = 3.6

x = 1.2

T-T this took waaaaaay too long to be helpful but I hope it is anyways!

The answer is 1.2 each side on the bigger shape that correlated with that side on the smaller shape, can be scaled down by a certain amount to get a value for that particular side. So in this problem you would do 2/1.666666666666667 Wich equals 1.2

A project to build a new bridge seems to be going very well since the project is well ahead of schedule and costs seem to be running very low. A major milestone has been reached where the first two activities have been totally completed and the third activity is 60 percent complete. The planners were expecting to be only 50 percent through the third activity at this time. The first activity involves prepping the site for the bridge. It was expected that this would cost $1,420,000 and it was done for only $1,300,000. The second activity was the pouring of concrete for the bridge. This was expected to cost $10,500,000 but was actually done for $9,000,000. The third and final activity is the actual construction of the bridge superstructure. This was expected to cost a total of $8,500,000. To date they have spent $5,000,000 on the superstructure. Calculate the schedule variance, schedule performance index, and cost performance index for the project to date.
