Answer:

x = 3

Step-by-step explanation:

y = 2/3 x + 5; y = 7

7 = (2/3)x + 5

2 = (2/3)x

x = 2 * 3/2

x = 3

Answer:

x=3

Step-by-step explanation:

To start all you need to do is replace [tex]y[/tex] with 7 to get [tex]7=\frac{2}{3}x+5[/tex]

Then, you need to isolate x on the right side of the equation, starting with subtracting 5 on both sides to get [tex]2=\frac{2}{3}x[/tex]

Finally, you divide both sides by [tex]\frac{2}{3}[/tex]. You divide fractions by multiplying the reciprocal like so [tex]\frac{2}{1} *\frac{3}{2} =x[/tex] to get [tex]\frac{6}{2} =x[/tex]. This means that x=3

Answer:

The angle of rotation pf a six sided star, that will carry the six sided star onto itself is 60°

Step-by-step explanation:

The angle of rotation that will carry a six sided star onto itself is the angle between two adjacent lines of symmetry of the six sided star

Given that there are three lines of symmetry of the six sided star, and each line intersect with the next line at the center of the figure, the angle between two adjacent lines of symmetry = 360°/(2 × 3) = 60°

Therefore, the angle of rotation pf a six sided star, that will carry the six sided star onto itself = 60°.

Answer:

Slope: -2; Y-intercept: 2

Step-by-step explanation:

To find the slope, you can rewrite the equation into standard form:

2x+y-2=0

2x+y=2

y=2-2x

The slope is the coefficient of x, which is -2. The y-intercept is the other number, which is 2.

Step-by-step explanation:

gradient= ‐2

y‐ik intercept=2

explanation: rearrange the equation to make y your subject

from the equation , you already know that ‐2 is m (from the equation y=mx +c , whereby m is your gradient) which means ‐2 is your gradient.

from your equation you would also know that 2 is your y‐intercept. also from the equation y=mx+c is your UK intercept

Answer:

180 students

Step-by-step explanation:

28 -13 = 15

15 tables times 12 students

Answer: 180 fifth grader

Step-by-step explanation:

Answer:

(-1,4)

Step-by-step explanation:

Because you look at the (Y,X) line first and then you see the Y is -1 and the X line is 4 and that will give you an answer as (-1,4)

Answer:

100

Step-by-step explanation:

Because everyone had one plate and one drink, we can combine those individual prices.

5 + 1 = 6

Now we divide 600, the total cost, by 6, the cost for one person.

600 ÷ 6 = 100

So now we know that 100 people went to the party, as there was nothing left over.

Answer:

uh I think x=25°

Step-by-step explanation:

2x+60°=110°(vertically opposite angles are equal)

2x=110°-60°

2x=50°

x=50°÷2

x=25°

Answer:

The value of y should be -10

Step-by-step explanation:

If x and y are proportional, then 8/12=y/-15

The fractions just show the y values over the x values

Cross multiply to get 12y= -120

y= -10

Answer:

The length of the rectangle is 14 cm

Step-by-step explanation:

Here, we want to find the length of the rectangle given the width

Mathematically, the perimeter of the rectangle can be calculated using the formula;

2( l + w)

from the question w = 10

and perimeter = 48

Thus;

2( l + 10) = 48

divide both sides by 2

l + 10 = 48/2

l + 10 = 24

l = 24 - 10

l = 14 cm

Answer:

1.85 X 10^14

Step-by-step explanation:

Answer:

Jack's birthday is in 56 days.

The jumps end at point 56 on the number line.

Step-by-step explanation:

Since one week has 7 days.

So, 8 week = 8 x 7 =56 days.

Hence, Jack's birthday is in 56 days.

On the number line, the current time is being represented by 0.

When I take one jump from 0, I will reach the point 1 on the number line, which corresponds to 1 day.

Again, in my 2nd jump from point 1 on the number line, the next point on the number line will be 2 which corresponds to 2 days.

This process repeats until I complete the 56 jumps to get point 56 on the number line, which corresponds to 56 days.

In this way, the number line can be used to solve.

Hence, the jumps end at point 56 on the number line.

Answer:

x < 1/2

x > -2

Step-by-step explanation:

We know that 4x + 3 < 5 and 4x + 3 > -5

4x + 3 < 5

~Subtract 3 to both sides

4x < 2

~Divide 4 to both sides

x < 2/4 or x < 1/2

4x + 3 > -5

~Subtract 3 to both sides

4x > -8

~Divide 4 to both sides

x > -2

Best of Luck!

Step-by-step explanation:

Answer:

∠COS = 30°

Step-by-step explanation:

∠BPO = 120° + x

∠COS = x

Alternate Interior/Exterior is congruent if two parallel lines are intersected by a transverse.

∠BPO = ∠COP

∠COP = 120° + x

∠COP + ∠COS = 180°

120° + x + x = 180°

120° + 2x = 180°

2x = 60°

x = 30°
