Answer:

x = -2

Step-by-step explanation:

You want to add 2x on both sides to get to this equation -3x - 2 = 4 with the -2 being negative due to having a positive and a negative sign turning into a negative number.  Add 2 on both sides to get -3x = 6.  Divide -3 on both sides to get your final answer or as your x value which is -2.

Answer:

Step-by-step explanation:

-5x - 2 = -2x + 4

-3x - 2 = 4

-3x = 6

x = -2

Answer:

(a) 40 m

(b) 4 seconds

(c) 1 second, 45 m

(d) 1 second

Step-by-step explanation:

The given height as a function of height is

[tex]h= -5t^2+10t+40[/tex]

where t is the time in seconds and h is the height, in meters.

(a) At the starting time, t=0, the arrow is at the platform.

So, putting t=0, to get the height of the platform

[tex]h= -5(0)^2+10(0)+40 = 40[/tex] m

(b) For determining the length of time the arrow is in the air, first t determining the value of t for which h=0, we have

[tex]-5t^2+10t+40=0 \\\\-t^2+2t+8=0 \\\\-t^2+4t-2t+8=0 \\\\-t(t-4)-2(t-4)=0 \\\\(-t-2)(t-4)=0 \\\\[/tex]

t=-2, t=4  

Mathematically, the value of t for which the arrow is in the air is the time from -2 to 4 seconds.

But the arrow was at the platform at time t=0. So, neglecting the negative time, the time for which the arrow was in the air is the time from 0 to 4 seconds, i.e 4 seconds.

(c) Mathematically, the value of t for which the arrow is in the air is the time from t=-2 to t=4 seconds. So, in the middle of time, i.e at t=1 second the arrow will reach the maximum height.

Putting t=1 to get the maximum height, we have

[tex]h=-5(1)^2+10(1)+40[/tex]

h=-5+10+40

h=45 m

Therefore, the maximum height is 45 m at t=1 second.

(d) Referinf option (c), at the time, t=1 second, the arrow has a height of exactly 45m above the ground

Answer:

50

Step-by-step explanation:

Let a = number of balls in bag A.

Let b = number of balls in bag B.

a = 1.2b

a - 5 = b + 5

1.2b - 5 = b + 5

0.2b = 10

b = 50

Answer: 50

Answer: the answer is 50

Answer:

The statement which is not true about the sample is;

The sample of 10 plants was a census of the corn plants

Step-by-step explanation:

The statement out of the given statements which is not true about the sample is "The sample of 10 plants was a census of the corn plants"

The 10 unique number corn which the farmer randomly selects of which he then count the number of ears in the corn and multiply by 100 so as to quickly arrive at an estimate of the total number of ears of corn for the crop, without individually counting the ears on each plant from the 100 plants

A census is a counting and individual enumeration procedure to collect and record characteristic information and details of the all the members that make up a given population

Therefore, the farmer is finding an estimate of the number of ears of in the plants rather than taking a census of the ears of corn on each plants in the population of 100 plants

Answer:

The sample of 10 plants was a census of the corn plants.

Answer:

2

Step-by-step explanation:

Given that:

Number of pizzas made = x

Total pizza sauce left = 1/3 L

Amount of sauce used on each pizza made = 1/6 L

Hence , Number of pizza's made ;

(Total pizza sauce left / amount of sauce used per pizza made)

= (1/3 L) ÷ (1/6)L

= 1/3 * 6/ 1

=6 / 3

= 2

Hence, number of pizza's made = 2

Step-by-step explanation:

first you go by counting by 2s and when your done it says one will ride alone so minus 1 that is 5 so the answer will be 5

Answer:

1. First choice, 1/2

2. First choice, 1/2

Step-by-step explanation:

3 odd numbers on a dice, so 3/6 = 1/2

12 numbers, 1- 12, the even numbers are 2, 4, 6, 8, 1-, and 12. 6 out of 12 = 6/12 = 1/2

Step-by-step explanation:

2 + x + 2x = 14

3x + 2 = 14 (combine like terms)

3x = 12 (subtract 2 from both sides)

Hence the answer is 3x = 12. (B)

Answer:

-6 is the answer.

Step-by-step explanation:

4x - 5 = x - 23

or, 4x - x = -23 + 5

or, 3x = -18

or, x = -18/3

therefore, x = -6

Answer:

the answer is (3)

Step-by-step explanation:

4x - 5 = x - 23

4x = x - 23 + 5

4x = x - 18

4x - x = -18

3x = -18

[tex] \frac{3x}{3} = \frac{ - 18}{3} [/tex]

[tex]x = - 6[/tex]

Answer:

Alisha can mow the lawn 5 times before refilling the container.

Step-by-step explanation:

We have the total amount of gas to mow the lawn and the amount needed to mow one lawn, so we need to divide.

3 3/4 divided by 3/4 =5

Therefore she can mow the lawn 5 times before refilling the container.

Answer:

answer: 711

711.403641819=P

On solving the provided question, we can say that - the value of the simple interest will be $ 881.28.

Multiplying the principal by the interest rate, time, and other factors yields simple interest. Simple return equals principle times interest times hours is the marketed formula. It is easiest to compute interest using this formula. A percentage of the principle balance is how interest is most commonly computed. The interest rate on the loan is known as this percentage.

here,

we have

P = 1360;

R = 5.4 ;

T = 12

so, we get,

SI = 1360 X 5.4 X 12 /100

SI =88128/100

= 881.28

Hence, On solving the provided question, we can say that - the value of the simple interest will be $ 881.28.
