Step-by-step explanation:

Answer:

The mixed number is 5  2 ÷ 3

Step-by-step explanation:

The computation of the number of yards of fabric does Jacob use is shown below:

Given that there is 17 yards of fabric

And, it used one third of it

So the number of yards would be

= 17 ÷ 3

= 5 2 ÷ 3

Hence, The mixed number is 5  2 ÷ 3

Answer:

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

−4(x−5)=92

Answer:

x=−18

Step-by-step explanation:

Answer:

x = 28

Step-by-step explanation:

4 ( − 5 ) = 9 2

4 − 2 0 + 2 0 = 9 2 + 2 0

4x =112

4x/4 = 112/4

x = 28

Answer:

10

Step-by-step explanation:

10/-5 = -2

-2+-2 = -4

Answer:

10

Step-by-step explanation:

First, arrange this word problem as an equation. Using N as the unknown number, we see:

(N/-5) + (-2) = -4

Next, we add -2 to both sides of the equation:

(N/-5) = -2

Now multiply both sides by -5:

N=10

(-5/3)/(1/6)=(-5/3)(6/1)=-30/3=-10

Answer:

-10.

Step-by-step explanation:

-5/3 / 1/6

= -30/3

= -10.

Answer:

1. I assume you just pick some arbitrary x and y numbers to plug in the equation. but if you answer part b and c first, part a might be easier for what values to choose.

2. if you do a quick browser search for how to find the max height of a parabola, then you can learn how to.

3. research on Browser. you can also just make y = 0.

vertex is max height, both zeros is just solving the equation for the x values. axis of symmetry is just the vertex point with a line through it.

Step-by-step explanation:

Answer:

$2.70

Step-by-step explanation:

to find out he marks up each shirt by, just do 45% of 6 or 0.45 * 6 = $2.70

If Jerry buys a t-shirt for $6 and sells it for 45% more than she bought it, then jerry is selling them for $8.70 and making $2.70 for each t-shirt she sells, because 45% of 6 is 2.7

You can find this answer by multiplying the percentage by the number (.45 x 6)

Step-by-step explanation:

Answer:

10

Step-by-step explanation:

Answer:

5.9 × 10⁻¹⁶

Step-by-step explanation:

To solve this, you need to  convert one of the two numbers to the same power of ten as the other.  We can do that by multiplying the first number by 10:

6.7 × 10⁻¹⁶ - 8.2 × 10⁻¹⁷

= 67× 10⁻¹⁷ - 8.2 × 10⁻¹⁷

= (67 - 8.2) × 10⁻¹⁷

= 58.8 × 10⁻¹⁷

= 5.9 × 10⁻¹⁶

Note that we're rounding to the nearest tenth, as the original numbers given were as well.

Answer:

Turning it 90 degrees clockwise.

Step-by-step explanation:

They are opposite, and 360 degrees is a complete turn. 360-270=90

Answer:

m and n are both equal to 10

Step-by-step explanation:

Because we see that the two of the angles here are 45 and 90, we know then that the third angle is also 45.  This tells us that the sides m and n are of equal length.

With that in mind, we can simply use the Pythagorean theorem to find their values:

m² + n² = (10√2)²

given that m = n, then:

m² + m² = (10√2)²

2m² = (10√2)²

2m² = 100 × 2

2m² = 200

m² = 100

m = 10

So both m and n are equal to 10.

Answer:

[tex]x = 4[/tex]

[tex]ac = 56[/tex]

Step-by-step explanation:

[tex]6x + 3 = 7x - 1[/tex]

[tex]7x - 6x = 3+ 1[/tex]

[tex]6x + 3 + 7x + 1 = 56[/tex]

[tex]x = 4[/tex]

-3(2x+7)+(-5x+6)-8(1-2x)-(x-3)=0

-6x-21-5x+6-8+16x-x+3=0

-6x-5x+16x-x=21+6-8+3

4x=22

x=5.5

Answer:

180-79-37=101-37=64

y=64 degrees

Answer:

y = 64

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the given angles and equate to 180

y + 37 + 79 = 180

y + 116 = 180 ( subtract 116 from both sides )

y = 64

Answer:

C. 21+ 25 = 180°

Answer:

x=4, y=-4/3. (4, -4/3).

Step-by-step explanation:

8x+9y=20

x=-3y

---------------

8(-3y)+9y=20

-24y+9y=20

-15y=20

y=20/-15

simplify

y=-4/3

x=-3(-4/3)=12/3=4

Answer:

Y=4/-3 X=4

Step-by-step explanation:

We must use substitution. If x is -3y, then we can either substitute all the x’s or y’s. I’ll substitute y.

8x+9y=20

8x+-3x=20

5x=20

x=4

x=-3y, so -3y=4. Y=4/-3

Answer:

D. Neither

Step-by-step explanation:

Ok so,

lets plug in the ordered pairs to see if the answer matches up. It should look like this:

7 = -2 - 5

7 = -7      DOES NOT MATCH; INCORRECT

now lets do it with the other ordered pair

-7 = -4 -5

-7 = -9        DOES NOT MATCH; INCORRECT

hope this helps, have a good day!

Step-by-step explanation:

Answer:

[tex]12h\geq 60[/tex], [tex]h\geq 5[/tex]

Step-by-step explanation:

Speed of Jake [tex]=12[/tex] miles per hour

Let [tex]h[/tex] denotes the number of hours he should ride in order to meet or exceed his goal.

Distance travelled by Jake = Speed × Time = [tex]12h[/tex]

Jake has a goal of riding his bike at least 60 miles.

Therefore,

[tex]12h\geq 60[/tex]

[tex]h\geq \frac{60}{12} \\\\h\geq 5[/tex]

Answer:

The solution of the system of equation is (3,8)

Step-by-step explanation:

We are given that

[tex]y=x+5[/tex]...(1)

[tex]y=2x+2[/tex]...(2)

We have to graph the system of linear equation.

For equation (1)

Substitute x=0

[tex]y=5[/tex]

Substitute y=0

[tex]x=-5[/tex]

Therefore, we obtained two points  (0,5) and (-5,0) for equation (1).

For equation (2)

Substitute x=0

[tex]y=2[/tex]

Substitute y=0

[tex]2x=-2[/tex]

[tex]x=-1[/tex]

Therefore, we obtained two points  (0,2) and (-1,0) for equation (2).

Now, we find intersection point of two equation

Substract equation (2) from (1)

[tex]x=3[/tex]

[tex]x=3[/tex]

Substitute x=3 in equation (1)

[tex]y=3+5=8[/tex]

The intersection point of two equation is at (3,8).

Hence, the solution of given system of equation is (3,8).

Answer:

(-4,-6)

Step-by-step explanation:

The intersection point is (-4,-6) when you both equations in the calculator. The person who answered this first is wrong.
