Let's solve your equation step-by-step.
<span><span><span><span><span>3m</span>+<span>1m</span></span>−7</span>+<span>3m</span></span>=21
</span>Step 1: Simplify both sides of the equation.
<span><span><span><span><span>3m</span>+<span>1m</span></span>−7</span>+<span>3m</span></span>=21
</span><span>Simplify: (Show steps)
</span><span><span><span>7m</span>−7</span>=21
</span>Step 2: Add 7 to both sides.
<span><span><span><span>7m</span>−7</span>+7</span>=<span>21+7
</span></span><span><span>7m</span>=28
</span>Step 3: Divide both sides by 7.
<span><span><span>7m/</span>7</span>=<span>28/7

An equation is formed of two equal expressions. A point that will lie on the line 3x-8y=54 is (5,-4.875).
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
To find a point on the line 3x-8y=54, take any random value of x and substitute for the equation, and solve the equation for y. Now, as you have the value of x and y, you have the coordinate of the point.
Let the value of x be 5.
3x-8y=54
3(5)-8y =54
15-8y = 54
-8y = 54 - 15
-8y = 39
y = -4.875
Hence, a point that will lie on the line 3x-8y=54 is (5,-4.875).

Answer:
D) 3:10
Step-by-step explanation:
Well only blues and yellows are at least $5. there are 25 yellows and 5 blues and if you add them together there's 30 in total. Now compare that 30 to 100 and you have 30:100. In the simplest form you have to divide both sides by 10 and it becomes 3:10.
