Answer:

- 15

Step-by-step explanation:

[tex] \frac{1}{3} a = - 5 \\ \\ a = - 5 \times 3 \\ \\ a = - 15[/tex]

Answer:

-15

Step-by-step explanation:

As you can see, the denominator of 1/3 is 3. 1 third of a is -5. So what you do is, you multiply -5 * 3 and that'll give you -15. So, it is equal to -15.

Answer:

x =7

Step-by-step explanation:

To solve this, you must get x by itself.

3x-5 = 16      1.  Add 5 on both sides

3x = 21         2. Divide by 3 on both sides

x = 7

Step-by-step explanation:

Answer:

67 cm

Step-by-step explanation:

We are given the initial height of the plant let's call it H.

H = 54 cm. This is the original height of the plant at M(months) = 0.

We are given that it grows at 1 cm/month. This is the rate of growth.

Rate = 1

Time (M) is given in Months.

So when M = 0, H = 54

Let's say M = 1, That is one month has passed. In this time the plant's height would have increased by 1 cm. So our plant's height would be H = 54+1 = 55 cm.

When Two months have passed our plant's height would be H = 54 + 2 = 56 cm , since every month our plant gains 1 cm in Height, we can make a fuction for this.

H = 1M + 54.

Now we just plug in 13 for M, to get 13 months.

H = 13 + 54

H = 67 cm

So our plant would be 67 cm in height after 13 months.

Answer:

the answer is 5 3/8

Step-by-step explanation:

the common denoiminator of 4 and 8 is 8 so you multiply 3 by 2 like you did 4 to get 8 and you multiply 5 by 1 like you did 5 to get 5 and you add it all together

Answer:

y = 4x+3

Step-by-step explanation:

The equation in point slope form is expressed as y - y0 = m(x-x0)

m is the slope

(x0, y0) is the point on the line

If a line is parallel to y = 4x + 1, the slope of the line m = 4

Substitute m = 4 and the point (-2, -5) into the equation above;

y - (-5) = 4(x - (-2))

y+5 = 4(x+2)

y+5 = 4x+8

y = 4x+8-5

y = 4x + 3

Hence the equation of the line is y = 4x+3

Answer:

16 turtles

20 frogs

32 fish

Step-by-step explanation:

let 't' = # turtles

let '4 + t' = # frogs

let '2t' = # fish

t + 4 + t + 2t = 68

4t + 4 = 68

4t = 64

t = 16 turtles

4 + 16 = 20 frogs

2(16) = 32 fish

Answer:

130°

Step-by-step explanation:

∠JDG and ∠EDF are opposite angles. The measures of arcs for opposite angles always add up to 180°. Since the arc for ∠JDG is 50°, the arc for ∠EDF has to be 130°, because 50 + 130 = 180.

Answer:

C) 5/3

Step-by-step explanation:

The ratio comparing red to blue marbles can be created by putting 5 and 3 together, since there are 5 red marbles and 3 blue marbles

This gets you 5/3

So, the correct answer is C) 5/3

Answer:

5/3

Step-by-step explanation:

This is because there are 5 red marbles and there are 3 blue marbles. If you put them side by side, the ratio is 5:3 or 5/3.

Answer:

I believe the answer is the first one. definitely not the third or fourth. and it should only be exponented by t not 2t because then it'd be double what you should have.

Answer:

Distance B = 1275 kilometers.

Step-by-step explanation:

Let the two distances and time be A and B respectively.

Given the following data;

Distance A = 17 kilometers.

Time A = 8 minutes.

Distance B =?

Time B = 60 minutes.

First of all, we would find the constant speed;

Speed = distance/time

Substituting into the equation, we have;

Speed = 17/8

Speed = 2.125 km/m

Now, to find the distance B;

Distance B = speed * time

Distance B = 2.125 * 60

Distance B = 1275 km
