First, let's simplify the sentence:
3x+16 = 14x+28+x
3x + 16 = 15x + 28
Then we isolate x on one side:
12x = -12
x = -1

Pls help due in an hour
BlackZzzverrR [31]

Answer:

4) Yes

5) Yes

6) Yes

7) No

Step-by-step explanation:

4) When we look at the table in the question, we can see the pattern is comics x 3 = price.

We know the definition of a proportional relationship is when one number is increased, the other is as well. So, it is in a proportional relationship.

5) We do the same thing here, we notice that we can divide the number of bikes by 5 to get the number of trips.

So, this is a proportional relationship.

6) The same reasoning applies to 6, we can see they follow a pattern.

7) All of them can be multiplied by 2, except the last one can't, so this is NOT a proportional relationship.

Solve for the indicated arc or angle in the diagram and match it to the correct solution at the bottom of the page.
hjlf

Answer:

106°

Step-by-step explanation:

The angle CAB is an inscribed angle of the arc mBC, so we have that:

mBC = 2*CAB

So we have that mBC = 2*37 = 74°

The segment AC is a diameter of the circle, so mAC = 180°

The ? angle is the arc mAB, which is the difference of mAC and mBC, so:

mAB = mAC - mBC = 180 - 74 = 106°

So the ? angle is 106°.

Find the equation for (0,4)and (7,-10 )
sweet [91]

Answer:

y = -2x + 4

Step-by-step explanation:

First find slope:

\frac{y_2-y_1}{x_2-x_1}=\frac{-10-4}{7-0}= \frac{-14}{7}=-2\frac{y_2-y_1}{x_2-x_1}=\frac{-10-4}{7-0}= \frac{-14}{7}=-2

We know equation of a line is y = mx + b, where m = slope and b = y-intercept, so we can plug in the slope:

y = -2x + b

The y-intercept of the equation is 4 because the coordinate (0, 4) is given. Therefore, the equation is:

y = -2x + 4

Find the surface area of a cuboid whose sides are 3cm by 6cm by 10cm
Brilliant_brown [7]

Answer:

216 cm²

Step-by-step explanation:

Use the formula for the surface area of a cuboid.

SA = 2lw + 2lh + 2hw

2(6)(3) + 2(6)(10) + 2(10)(3)

36 + 120 + 60

= 216

The surface area of the cuboid is 216 cm².
