Answer:

6

Step-by-step explanation:

2/3x=4

then 4/ 2/3 (you can just input this in a calculator)

it equals 6!

Answer:

x=6

Step-by-step explanation:

2/3x + 3 = 7

subtract 3 from both sides to get

2/3x = 4

divide 2/3x by 2/3 to isolate the variable

2/3x ÷ 2/3 = 4

what you do to one side you do to the other, so divide 4 by 2/3 as well, then you get

2/3x ÷ 2/3 is x

4 ÷ 2/3 is 12/2 which is equal to 6.

x=6

Step-by-step explanation:

2 dollars multiplied by every ride he rides, which is represented as x, and 5 dollars to just get in, which is a flat price, it doesn't change.

2x+5

Answer:

y=5+2x

5 is only one time. 2 for every ride. Ride is x for how many times you'll ride

Answer:

167oz

Step-by-step explanation:

There are 16oz in 1 lbs so we multiply the 10lbs by 16 to get oz.

10lbs * 16oz = 160oz

Now we add the 7oz because that's already in the correct unit.

160oz + 7oz = 167oz

Answer:

a = 4/3 b

Step-by-step explanation:

2a - b = 3b – a

Add a to each side

2a+a - b = 3b – a+a

3a -b = 3b

Add b to each side

3a -b+b = 3b+b

3a = 4b

Divide each side by 3

3a/3 = 4b/3

a = 4/3 b

Answer:

a = 4/3 b

Step-by-step explanation:

2a - b = 3b – a

Add a to each side

2a+a - b = 3b – a+a

3a -b = 3b

Add b to each side

3a -b+b = 3b+b

3a = 4b

Divide each side by 3

3a/3 = 4b/3

a = 4/3 b

Answer:

(-2,-1)

Step-by-step explanation:

3-5=-2

-4+3=-1

The coordinate of the point S if the point is translated 5 units left and 3 units up are (-2,-1). The correct option is A.

A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.

Given the coordinate (3,-4) of the point S. Now, if the point is translated 5 units left and 3 units up, then the new coordinates of S are,

(3,-4) → (3-5 , -4+3) = (-2, -1)

Hence, the coordinate of the point S if the point is translated 5 units left and 3 units up are (-2,-1).

Answer:

The change in height is 6/10 miles per hour and the entire descent will last 150 minutes (2 hours and 30 minutes)

Step-by-step explanation:

The gilder started 1 1/2 miles above the ground, in other words, it started [tex]\frac{15}{10}[/tex] miles above the ground. After 60 minutes it is now [tex]\frac{9}{10}[/tex] miles above the ground.

Therefore, the change in height in one hour is: [tex]\frac{15}{10}-\frac{9}{10}= \frac{6}{10}[/tex] miles.

Now, we know that the glide descends at a rate of 6/10 miles per hour, we can solve the second part of the problem using the rule of three (or proportions)

If it takes it 60 minutes to descend 6/10 miles, how long it will take it to descend 15/10 miles?

60 minutes --- 6/10= .6

x minutes ---- 15/10= 1.5

Therefore [tex]x=\frac{60(1.5)}{.6} =\frac{90}{0.6} =150[/tex] minutes

Thus, the entire descent will last 150 minutes.

Answer:

Step-by-step explanation:

First known equation is:

2L + 2W = 46

Second equation is:

L = W +7

Put the variable L of the second equation in the first equation.

2(W+7) + 2W = 46

2W +14 +2W = 46

4W = 32

W=8

Then resolve L using any of the above initial equations

L = 8 + 7 = 15

Verify: 2L +2W = 46

2(15) + 2(8) = 30 + 16 = 46 = perimeter

Step-by-step explanation:

Let the length = 7x

Let the breadth = x

As we know that

perimeter of rectangle =2(l+b)

Also perimeter here = 78 inches

Acc. to question

2(l+b) = 78 inches

[tex]2(7x + x) = 78[/tex]

[tex]16x = 78[/tex]

[tex]x = \frac{78}{16} [/tex]

[tex]x = 4.8[/tex]

so bredth = 4.8 approx

Answer:

1 : 2 : 5

Step-by-step explanation:

Each quantity must be expressed in the same units of measure, thus

1 litre = 100 ml and 2.5 litres = 2500 ml , then

500 : 1000 : 2500 ← divide each part by 500

= 1 : 2 : 5 ← in simplest form

Given :

Line WX bisects YZ at point W.

[tex]WZ=9\dfrac{5}{8}=\dfrac{77}{5}[/tex] .

To Find :

The length of YZ .

Solution :

Since , the point W bisect YZ .

So , it cuts YZ into two equal parts i.e YW and WZ .

Therefore , YW = WZ

Also , YZ = YW+WZ = 2WZ

[tex]YZ = 2\times \dfrac{77}{5}\\\\YZ=\dfrac{154}{5}\\\\YZ=30\dfrac{4}{5}[/tex]

Hence , this is the required solution .

Answer:

The atomic number is the number of protons (12) and the mass number is the number of neutrons and protons combined. So you'd subtract 12 from 25 (25-12=) and that'd get you 13 as your answer. If you need to find the number of electrons, it'll be the same as the number of protons unless it has a certain charge and if it does, if it's positive it has more protons (+) than electrons (-), if it is negative it has more electrons (- negatively charged) than protons (+ positively charged)
