Answer:
b
Step-by-step explanation:
Blue balls : Total number.
Total number of balls = 50 + 45 + 65 = 160
Blue balls : Total number.
= 65: 160 Divide both by 5.
= 13 : 32
= 13/32. That is the ratio.
Answer:
z−181=−170
Step 1: Add 181 to both sides.
z−181+181= −170+181
z=11
f(x) = 5x + 1
f(4) = 5 * 4 + 1
f(4) = 20 + 1
f(4) = 21
g(x) = 2x² - 3x +1
g(5) = 5 * 5² - 3 * 5 + 1
g(5) = 125 - 15 + 1
g(5) = 111
f(4) + g(5) = 21 + 111 = 132
Step 1: find two numbers that multiply to give ac ( in other words a x c ) and add to give b
step 2: rewrite the middle with those numbers
step 3: factor the first two and last two terms separately
step 4: if you’ve done this correctly, your two new terms should have a clearly visible common factor
and then you’re done! hope this helps!
