He only wants to pay 65$ and he already spends 45$ on his phone already. So you only have 20 dollars until his grand totaly of 65$ so 5x4= 20 so he can only use 4 gigabytes. Does that make sense? Hope I helped eheh
Answer:
When solving a simple equation, think of the equation as a balance, with the equals sign (=) being the fulcrum or center. Thus, if you do something to one side of the equation, you must do the same thing to the other side. Doing the same thing to both sides of the equation (say, adding 3 to each side) keeps the equation balanced.
Solving an equation is the process of getting what you're looking for, or solving for, on one side of the equals sign and everything else on the other side. You're really sorting information. If you're solving for x, you must getx on one side by itself.
Addition and subtraction equations
Some equations involve only addition and/or subtraction.
Example 1
Solve for x.
x + 8 = 12
To solve the equation x + 8 = 12, you must get x by itself on one side. Therefore, subtract 8 from both sides.

Step-by-step explanation:
They want the radius of Venus. With this info you know that Earth is 6378.1 km and Venus is 326.1 km smaller than that. So you would subtract 326.1 from 6378.1 6378.1-326.1=6052 therefore 6052 km is your answer.
Answer:
$3.63
Step-by-step explanation:
Let the price be P. We know that:
P = 15.99 $/kg If you multiply this value by the relation between pounds and kilograms:
P = 15.99 $/kg * 1kg /2.2 pounds = 7.27 $ /pounds
Now we can calculate the price of 1/2pound as:
P = 7.27 $/pounds * 1/2 pound = 3.63$
