Answer:

An equivalent expression is n x a = a + a + a + a... (a added n times).

Step-by-step explanation:

Given: expression for n x a.

To find: write an equivalent expression using only addition.

Solution: n x a means adding a to itself n times.

Thus n x a = a + a + a + a... (n terms).

Example: 3 x 2 = 2 + 2 + 2 = 6 (true).

Therefore, n x a = a + a + a + a... (n times).

Assume n and a are integers (or real numbers).
We can express an product of the form:
n * a

as the sum of a repeated n times.
For example:
For n = 4 and a = 3 we have:
4 * 3 = 12

Equivalently:
4 * 3 = 4 + 4 + 4 = 12

Answer:[[TAG_3],[TAG_4],[TAG_5]]B

Step-by-step explanation:

Given that QR is the median and measures 12, while NO measures 8, the difference is 12-8=4.

Thus, I will state that 2x+6 equals 16.

Setting the equation as 2x+6=16

2x=10

Street sweeping vehicles can clean 3 miles of streets per hour. A city owns two street sweepers, and each sweeper can be used fo
AnnZ [12381]
We know that
In a span of 4 hours (comprising 3 working hours and 1 hour for refueling)
each street sweeper can clean------> 3 miles*3 =9 miles

divide 18 hours by 4
18/4=4.5
4.5 equates to 4 cycles of 4 hours plus 2 hours

Multiply 4 by 9 miles
4*9=36 miles

within the 2-hour timeframe (<span>in this time, no refueling occurs)
</span>3*2=6 miles

each street sweeper can cover in 18 hours-----> (36+6)-----> 42 miles
two street sweepers will clean in 18 hours=2*42------> 84 miles

the result is
84 miles

I hope this helps... 25/100 x 79 = 19.75, then 79 - 19.75 = 59.25 (before tax). Calculating the tax, 7/100 x 59.25 equals 4.15, so 59.25 + 4.15 gives a total of 63.40 (after including tax). In order to find the final price after applying the discount and tax, the discount amount needs to be deducted from the initial price, then the relevant sales tax is added to the discounted total.
