4(x+5)-10 = 54

4x + 20 - 10 = 54

4x + 10 = 54

4x = 54 - 10

4x = 44

x = 44/4

x = 11

Answer:

x=11

Step-by-step explanation:

Using PEMDAS, you start by distributing the 4 among (x+5)

4*x=4x, 4*5=20

so you are left with 4x+20-10=54

simplify like terms (20-10=10)

this leaves you will 4x+10=54

Now you need to solve for x by moving everything else to the other side of the equal sign

to get rid of +10 on the left side, you must subtract 10 on both sides

4x=44

Now to get rid of the four, divide both sides by 4

x=11

3. Given ABCD ≅ FGHJ and mC = 9x - 7, mH = 5x + 13, find the value of x and the measures of angle C and angle H. Show all work
Bas_tet [7]
Since congruence and similarity for polygons is posted in a specific order, we know that angle A=angle F, side A=side F, die B=side G, and so on. Therefore, we have that angle C=angle H = 9x-7=5x+13. Subtracting 5x from both sides to separate the x using the subtraction property of equality, we get 4x-7=13. Next, we can add 7 to both sides to get 4x=20, and divide both sides by 4 to isolate the x and get x=5. Plugging that into angle C or angle H, we get that 9x-7=9*5-7=45-7=38=5*5+13.
