33% of decrease.
150-100=50
50 is 1/3 of 150
1/3= 33%
Convert the percentages in decimals:
90/100 = 0.9, 20/100 = 0.2
Multiply the decimals:
0.9 times 0.2 is 0.18, or 18%
Greg has an 18% chance of being elected both positions.
The answer is 7x = 6(x + 15)
x - Jim's rate
y - Pete's rate
<span>Jim completed half the floor in 7 hours: 7x = half of the floor
</span><span>Pete completed the other half of the floor in 6 hours: 6y = half of the floor
So: 7x = 6y
</span><span>Pete can lay 15 more tiles per hour than Jim: y = x + 15
</span>7x = 6y
y = x + 15
Substitute the second equation into the first one:
7x = 6(x + 15)
Answer:
Word problem based that can be solved using multiples to estimate the quotient:
Melissa made 326 cupcakes. She packed four cupcakes into each box. How many boxes of cupcakes did she pack? How many cupcakes were left unpacked?
Answer:
x = 35°
Step-by-step explanation:
Same side interior angles are supplementary, or they add up to 180°. So write an equation:
Solve for x. Subtract 145 from both sides:
The value of x is 35°.
