7x+1 + 4x-3 = 42
11x-2=42
11x=44
Divide by 11 on both sides which equals:
x=4
To find the length of DE just plug 4 in for x into the equation:
(7x+1) —> 7(4)+1= 29
29 is the length of DE
Then plug in 4 to EF’s equation:
(4x-3) —> 4(4)-3=13
13 is the length for EF
29+13= 42
So in the end, your answer will be 29.
Triangle area is 1/2 bh
So 11.9 is about 12, 7.1 is about 7.
7x12 = about 84 sq, cm

Read the article and review the phases of mitosis.
Mitosis
What are the four phases of mitosis?
prophase
metaphase
anaphase
telophase
cytokinesis
Answer:
X=12
Step-by-step explanation:
simplify both sides of the equation then isolate the variable.
5/2(12)-7=23
3/4(12)+14=23
making both equations equal to each other.
Answer:
She spent $70.65.
Step-by-step explanation:
Represent the amount spent by x.
Then $22.50 - x = -$48.15.
Combining like terms, we get:
$22.50 + $48.15 = x, or
x = $70.65
She spent $70.65.
