Answer:
11 nickels, 15 dimes, 22 quarters
Step-by-step explanation:
number of nickels = x
number of dimes = x+4
number of quarters = 2x
- - - - - -
total of nickels = 5x cents
total of dimes = 10x + 40 cents
total of quarters = 50x cents
- - - - - -
755 = 5x + 10x + 40 + 50x
755 = 65x + 40
715 = 65x
x = 11
x+4 = 15
2x = 22
Answer:
x = 30
Step-by-step explanation:
because the interior angles of a triangle = 180° so if you subtract 90° you get 90. in order to get 90 you can use the equation x + 2x = 90 which you will then get x = 30
Answer:
x = 41
Step-by-step explanation:
vertical angles are congruent , then
3x = 123 ( divide both sides by 3 )
x = 41
The product that will give a negative answer is: −3 × 4 × (−2) × (−7) = -168.
<h3>How to Find the
Product of Negative Numbers?</h3>
The rule when multiplying two negative numbers is that, the negative signs will cancel each other. That is, minus multiplied by minus will give as plus.
For example, -a × -b = ab
Also, "plus" multiplied by "minus" will also give as "minus. For example:
-a × b = -ab.
Using the above rule, let's find the product of the following:
−3 × 5 × (−6) × 4 = -15 × (-24)
−3 × 5 × (−6) × 4 = 360 [minus × minus = plus]
−7 × (−3) × (−9) × 0 = 0 [anything multiplied by 0 must result to 0]
−4 × (−6) × (−3) × (−5)
= 24 × 15
−4 × (−6) × (−3) × (−5) = 360
−3 × 4 × (−2) × (−7)
= -12 × 14
−3 × 4 × (−2) × (−7) = -168
Therefore, the product that will give a negative answer is: −3 × 4 × (−2) × (−7) = -168.
