Consider the system of linear equations −4x+2y=4 and 4x−y=−6. Which is different?

Answer:

Step-by-step explanation:

−2.7f+0.31−14−5

=−2.7f+0.31+−14+−5

Combine Like Terms:

=−2.7f+0.31+−14+−5

=(−2.7f)+(0.31+−14+−5)

=−2.7f+−18.69

Answer:

Answer:

The answer is 11,374

Step-by-step explanation:

First we find 5% of 9,400 is.

9,400 * 5% = 470

Next we add 9,400 with 470 then multiply by 20%

9,400 + 470 = 9,870

9,870 * 20% = 1974

Next we add.

9,870 + 1,974 = 11,374

So, the answer is 11,374

what is 2 times 5 minus 1?

9

Answer:It should be 5/9 as its the only one that is probable,

Step-by-step explanation:

If its not 1/2 its not 9/10 so that automautically declines 2 answers leaving 5/18 and 5/9. And 5/18 is way to little for a 36 to 20 ratio, so that leaves 5/9.

Answer:

Step-by-step explanation:

For an algebra question like this you are trying to solve for the x.

The way you do that is to get x by itself.

So with

17 = x - 28

The step you want to do is to add 28 to both sides.

17 + 28 = x - 28 + 28

This makes makes the equation

17 + 28 = x

45 = x

Answer:

35

Step-by-step explanation:

Let's solve your equation step-by-step.

17=x−18

Step 1: Flip the equation.

x−18=17

Step 2: Add 18 to both sides.

x−18+18=17+18

Step-by-step explanation:

0.3398

Answer:

Answer vary :

0.3398

Step-by-step explanation:

honestly in my opinion that’s my answer.

1. multiply (0.54 times 0.28) = 0.1512

2. multiply (0.46 times 0.41) = 0.1886

3. add 0.1512 + 0.1886 = 0.3398

and that’s how I did it.

Answer:

PQ = 64

Step-by-step explanation:

PQ = PK + KQ

10x - 16 = 6x + 8 + 8

10x - 16 = 6x + 16

4x = 32

x = 8

PQ = 10(8) - 16

     = 80 - 16

     = 64

Step-by-step explanation:

2a+26°+58°=180°

2a=180-26-58

2a=96

a=48

2*48+26=122

Given :

▪︎Measure of an angle in a parallelogram = 58°

▪︎Measure of the angle opposite this angle = (2x+26)°

We know that :

▪︎Opposite angles in a parallelogram are equal.

Which means :

[tex] =\tt 2a+ 26 = 58[/tex]

[tex] =\tt 2a = 58 - 26[/tex]

[tex] =\tt 2a= 32[/tex]

[tex] =\tt a = \frac{32}{2} [/tex]

[tex]\hookrightarrow\color{plum}\tt a = 16[/tex]

Thus, the value of a = 16

Let us now place 16 in the place of a and check whether or not we have found out the correct value of a:

[tex] =\tt 2 \times 16 + 26 = 58[/tex]

[tex] = \tt32 + 26 = 58[/tex]

[tex] =\tt 58 = 58[/tex]

Since the values in both the side match, we can conclude that we have found out the correct value of a.

▪︎Therefore, the value of a = 16

pls thanks

Answer:

16

Step-by-step explanation:

Recall that the product of a negative number and another negative number is a positive number.  Thus, -(-5) = +5, and the original expression becomes

6.9 + 5 + 4.1​.

Combining the mixed numbers 6.9 and 4.1, we get 11.

Combining 11 and 5 results in 16.

Answer:

243

Step-by-step explanation:

Answer:

243

Step-by-step explanation:

The height is 7.04 feet at the rafter's peak that makes an angle of 28° and 15 feet long.

An angle is the formed when two straight lines meet at one point, it is denoted by θ.

Given that,

Length of rafter = 15 feet,

Angle made by rafter with the horizontal = 28°

Apply sin formula to determine the length x of the rafter,

sinθ = x / 15

sin28°  = x / 15

0.469 = x / 15

x = 7.04

The height of the rafter is 7.04.

Step-by-step explanation:

9^2-6^2

√45

b= ✓45

Answer:

162

Step-by-step explanation:

a=[tex]\frac{a+b}{2} h[/tex]

a=base and the base is 13 ft.

b= also means base which is 23 ft.

h= height which is 9 ft.

so 13+23 is 36

36/2 is 18

and 18 times 9 is 162
