The solution of the expression is -1 ⇒ 3rd answer
Step-by-step explanation:
Let us revise some important rules on the number line
- If we add number to another number we move to right
- If we subtract a number from another number we move to left
∵ The expression is negative 2 minus 3 minus (negative 4)
∵ negative 2 = (-2)
∵ minus means (-)
(-2) minus 3 means move 3 units from (-2) to left, so you will pass -3, -4, and stop at -5
∴ (-2) - 3 = -5
∵ minus (negative 4) = - (-4)
- Remember (-)(-) = (+)
∴ minus (negative 4) = + 4
That means move 4 units to the right from -5, then you will pass -4, -3, -2, and stop at -1
∴ -5 + 4 = -1
∴ The expression (-2) - 3 - (-4) = -1
The solution of the expression is -1

Answer:
<h2>10.7%</h2>
Step-by-step explanation:
Step one:
given
expected weight= 28pounds
Actual weight= 25 pound
Required:
percent error
δ= percent error
vA =actual value observed
vE =expected value
δ=25-28/28*100
δ=-3/28*100
δ=0.107*100
δ=10.7%
The percent error is 10.7%
For the given linear equation:
- The constant term represents the cost of the sneakers.
- The linear term represents the cost of the laces.
<h3>What does each part of the expression represent?</h3>
We know that Sarah buys one pair of sneakers and several pairs of laces.
We know that the amount that she spends is:
$35 + $3*l
The first term, the constant one, represents the cost of the pair of sneakers.
The linear term:
$3*l
Represents the cost of buying l pairs of laces, assuming that each pair costs $3.

The angles don’t change since the triangle was dilated by a factor
X=30
Y=60
Z=90
The trick to this question is the find the least common multiple of 20 and 15. You could do 20×3=60 and 15×4=60 as those both equal the same number yet you there are no other multiples they share before 60. So the next time the two schools will eat pizza on the same day again will be in 60 days. Hope this helps!
