Answer:

2×x×7+3x=12

2x+14+3x=12

5x+14=12

5x=12-14

5x=-2

Divided Both Sides By 5

X=-2/5

Answer is down below.

Step-by-step explanation is in the photo below.

Step-by-step explanation:

Solution,

∠IDJ = 70° ( being alternate angle in AB || CD )

∠ IDJ + x = 180° ( being co-interior angle in EF || GH )

or , 70° + x = 180°

or , x = 180° - 70°

x = 110°

Again,

∠BLH = ∠CKG ( Being alternate angle in AB || CD )

y = 110°

Finally ,

z + y = 180° ( Being adjacent supplementary angle )

or , z + 110° = 180°

z = 70°

Thus , x = 110 ° , y = 110 ° and z = 70°

Answer:

8 cookies left to be baked.

Step-by-step explanation:

Together both of them bakes = (1/3) + (2/5)

                                                 =  [tex]\frac{5}{15} +\frac{6}{15}[/tex]

                                                 = [tex]\frac{11}{15}[/tex] cookies.

So they have baked: (11/15) * 30 = 22 cookies together.

cookies left to be baked: 30 - 22 = 8 cookies.

Answer:

Step-by-step explanation:

Cookies needed - 30.

Answer:

The number is 9

Step-by-step explanation:

• Let the number be x

[tex]{ \tt{3x - 7 = 20}} \\ [/tex]

» Add 7 to either sides following addition rule of equality:

[tex]{ \tt{(3x - 7){ \red{ + 7}} = 20{ \red{ + 7}}}} \\ { \tt{3x = 27}}[/tex]

» Divide either sides by 27:

[tex]{ \tt{ \frac{3x}{ \blue{3 }} = \frac{27}{ \blue{3}} }} \\ \\ { \tt{x = 9}}[/tex]

Answer:

2 × 1 +2 +2×2 =8

2+2+4=8

8=8

3×1 +3× -2 + 4×2 =5

3-6+8=5

5=5

1+2 × -2 +2 = -5

1-4+2= -5

-5 = -5

To make a perfect square of v² - 14v , add c such that:

We have:

⇒ v² - 14v + 49 = (v - 7)(v - 7) = (v - 7)²

Answer: 49

Answer:

Step-by-step explanation:

Let the speed of bird of species A is x and speed of B is y.

The equations:

Substitute and solve for y:

Find x:

[tex]x[/tex]will be the speed of species b and [tex]4x[/tex] will be the speed of species a:

[tex]x + 4x = 180[/tex]

[tex]5x = 180[/tex]

[tex]x = \frac{180}{5}[/tex]

[tex]x = 36 \: m/h[/tex]

If species b has a speed of [tex]36 [/tex]m/h, the speed of species a is [tex]4[/tex]times that:

[tex]4 \times 36 = 144 m/h[/tex]

Answer :—

[tex]A = 36 \: m/h [/tex]

[tex]B = 144 \: m/h[/tex]

Answer:

10/3 or 3 1/3

5/1 · 2/3 = 10/3

You can't simply this anymore farther.

Also the proper form of 10/3 is also 3 1/3.

Answer:

y=8x-13

Step-by-step explanation:

When you're finding a perpendicular line, you take the opposite of the slope. The slope in this equation is 1/8, so a perpendicular line will have the slope of 8. So we already know y=8x+b.

Plug in your x and y values from the ordered pair and you get -5=8(1)+b. 8×1 is just 8, so it's -5=8+b. Subtract 8 from both sides and you get -13=b.

Answer:

184 is the diameter

Step-by-step explanation:

Hi!

I can help you with joy!

Are these ordered pairs the same? Do they name the same point?

(8, -9) and (-9,8) are our points.

The x-coordinate of one point is 8, and the x-coordinate of the second point is -9.

The y-coordinate of the first point is -9, and the y-coordinate of the second point is 8.

Thus, these 2 ordered pairs do not name the same point.

The statement is false.

I hope this helps!

If it is rounded up.

to lease a new car, you must make a dowm payment when you sign the lease, then pay $199 per month . six months after signing his lease, Mr Scott had paid $2,694. write and solve an equation to find the total amount he will have paid after 3 years.

Answer:

The inequality that describes this problem is , and the minimum number of computers he must sell is 25.

Step-by-step explanation:

Since there is no restriction on the number of computers he must sell, an inequality can help us describe the situation.

Writing the inequality.

Let x be the number of computers he sells the next month, since he receives a bonus of $100 per computer he sells the total amount he will make for x computers is

And since he wants to make $2,500 in bonuses, the inequality that describes that situation is

Solving the inequality.

In order to find the exact number of computers he must sell, we need to solve for the inequality.

Since 100 is multiplying to x, in order to move that 100 to the other side, we need to apply the inverse operation to multiplication, which is division. We can then divide both sides by 100

So then we can simplify to get

Thus the minimum number of computers he must sell is 25.

Step-by-step explanation:

Answer:

(x+5)+(x-10)+(x-75)+125=360

3x+45=360

3x=315

x=105

Answer:

x = 80

Step-by-step explanation:

We have, 150% · x = 120

or, 150/100 · x = 120

Multiplying both sides by 100 and dividing both sides by 150,

we have x = 120 · 100/150

x = 80

If you are using a calculator, simply enter 120×100÷150, which will give you the answer.

[RevyBreeze]

Answer:80

Step-by-step explanation:

we have,

150x/100 = 120

x = 120 x 150/100

x= 80
