Answer:

394

Step-by-step explanation:

The largest number is 100 since it says none greater than 100. We can have 100

The next number is 99 since it is not equal to 100 and is the next largest number

The next number is 98 since it is not equal to 100 or 99 and is the next largest number

The last number is 97 since it is not equal to 100 or 99 or 98 and is the next largest number

The sum of the 4 numbers is

100+99+98+97 =394

Consider the equation below

s344n2d4d5 [400]

Answer: B

Step-by-step explanation:

Let's solve the given equation. Then we can see which other equation has the same answer.

-5n+31=-14n-5

36=-9n

n=-4

We need to fina another equation that gives n=4 as the answer.

A. Incorrect

3-6n+3n=-3+4-4n

3-3n=1-4n

n=-2

B. Correct

$\frac{11}{4} n+2=-3+\frac{3}{2}n$

$\frac{5}{4}n=-5$

$n=-4$

C. Incorrect

1=0.75n+3.25

-2.25=0.75n

n=-3

D. Incorrect

-1-22n=-20n-9

8=2n

n=4

Yesterday noah ran 2 1/2 miles in 3/5 hour. Emily ran 3 3/4 miles in 5/6 hour. Anna ran 3 1/2 miles in 3/4 hour how fast in mile

Dmitry_Shevchenko [17]

Answer:

Step-by-step explanation:

To calculate the speed of each one we proceed as follows:

speed=distance/time

a] Noah's speed:

distance=2.5 miles

time=3/5 hours

speed=(2 1/2)/(3/5)

=(5/2)/(3/5)

=5/2×5/3

=25/6

=4 1/6 mi/hr

Emily's speed

distance=3 3/4 miles

time=5/6 hour

thus

speed=(3 3/4)/(5/6)

=15/4)/(5/6)

=15/4×6/5

=4 1/2 mi/hr

Anna's speed:

distance=3 1/3 miles

time=3/5

speed=(3 1/3)/(3/5

=(10/3)/(3/5)

=10/3×5/3

=5 5/9 mi/hr

Anna was the fastest

During a baseball season, team a scores 9 runs for every 7 runs that team b scores. The total number of runs scored by both team

mrs_skeptik [129]

Answer:

∴ Team b scores is 630

And team a scores is 810

Step-by-step explanation:

Given;

Team a scores $9$ runs for every $7$ runs that team b scores.

Lets,

Think b is scores $x$ runs;

Then a is scores $x+(2\times\frac{x}{7} )$ ;

Because every 7 runs of b , a is scores more 2 runs.

Total number of runs scored by both teams is 1440

Runs score by team a + Runs score by team b=1440

$x+(2\times\frac{x}{7} )+ x =1440$

$2\times x+ \frac{2\times x}{7}=1440$

$\frac{(14\times x)+(2\times x)}{7} =1440$

$\frac{16\times x}{7} =1440$

$16\times x=1440\times 7$

$x=\frac{10080}{16}$

$x=630$

∴ Team b scores is 630

And team a scores is $630+(2\times \frac{630}{7} )=810$
