Its simple, the expression is 7+x and it does not have an equal sign since it is not an equation
Answer:
m∠1 = 68°
m∠2 = 68°
m∠3 = 112°
m∠4 = 112°
m∠5 = 68°
m∠6 = 68°
m∠7 = 112°
Step-by-step explanation:
<u>Vertical Angle Theorem</u>
When two straight lines intersect, the opposite vertical angles are congruent.
<u>Corresponding Angles Postulate</u>
When a straight line intersects two parallel straight lines, the resulting corresponding angles are congruent.
<u>Angles on a Straight Line</u>
Angles on a straight line sum to 180°.
Applying the Vertical Angle Theorem and the Corresponding Angles Postulate:
⇒ m∠3 = m∠4 = m∠7 = 112°
To find the measure of angle 2, apply the Angles on a Straight Line theorem:
⇒ m∠2 = 180° - 112° = 68°
Applying the Vertical Angle Theorem and the Corresponding Angles Postulate:
⇒ m∠2 = m∠1 = m∠5 = m∠6 = 68°
Answer:
- after 4.5 months (or 5)
- $795
Step-by-step explanation:
10% of $100 per month is $10 per month.
1. By saving $10 per month on insurance cost, Dan's savings after 4.5 months will be equal to the $45 cost of his course. (If billing is monthly, he won't experience any net gain from the course until the 5th insurance payment--after 5 months.)
__
2. In 7 years, the savings on insurance costs will total ...
(7 years)×(12 months/year)×($10 /month) = $840
His cost for the course is $45, so his net saving is ...
$840 -45 = $795 . . . net saving by age 25
To find the price of something with sales tax, you simply multiply it by 1.(percent as a decimal). The "1" represents the original price, while the decimal afterwards represents the percent of sales tax. In this case, 3% is .03 as a decimal, so we should be multiplying 55 by 1.03.
55
<u>x1.03
</u>56.65
<u>
</u>Using the math above, we can see that the price of the shoes with the sales tax is $56.65.<u>
</u>
D) It is the sum of the initial amount and the additional amount after d days.
He is adding them together to find the sum, not multiplying them together to find the product.
