The answer is B I think.

The answer for 15 > -3x would be x > -5.

1. Divide both sides by -3 (15/-3 < x)

2. Simplify 15/3 to 5 (-5 < x)

3. Switch sides (x > -5).

If x = 2/9 and y = 3/7 work out the value of x + y

faltersainse [42]

Answer:

$\boxed{\sf \dfrac{41}{63}}$

Step-by-step explanation:

hi, it means that we have to compute

$\dfrac{2}{9}+\dfrac{3}{7}=\dfrac{7*2+3*9}{7*9}=\dfrac{14+27}{7*9}=\dfrac{41}{63}$

I need to find the slope and b Y=mx+b HELP ME

Naddika [18.5K]

Answer:

$y=-\frac{4}{3}x+20$

Step-by-step explanation:

stupid enough

y=mx+b

$\frac{y1-y2}{x1-x2}$

slope = 16-12/3-6

-4/3

$y=-\frac{4}{3}x+b$

plug in x and y

16=-4/3(3)+b

b=20

] Complete the explanation of how you know whether the triangles are similar. If possible, find the Indicated length. A P 2.0 1.

disa [49]

1. The two triangles are similar because the two pairs of angles are equal, therefore the third angles of both triangles must also be equal.

We can call this the AAA similarity criterion

2. To find QR, we must use ratios between 2 known similar sides of both triangles,

$\frac{2.0}{1.7}=\frac{1.2}{QR}\text{ , QR=}\frac{1.2\times1.7}{2.0}=\text{ 1.02}$

So, QR =1.02

What is the probability that if you multiply two randomly-selected two-digit whole numbers, the result is greater than 100 and l

ohaa [14]

Answer:

4/675

Step-by-step explanation:

There can be 90 two-digit numbers ranging from 10 to 99. There will be

90 x 90= 8100 possibilities of randomly selecting and combining 2 entire two-digit numbers, if we find ax b to be distinct from bx a. When 10 is first chosen, there may be 9 two-digit numbers that could be combined within the required range for a product When 11 is chosen first, then the second two-digit number has 9 possibilities. 12 has seven options; 13 has six options; 14 has five options; 15 has four options; 16 has three options; 17 has two options; 18 has 2 options; and 19 has one option. It provides us 48 total choices so the likelihood that the combination of two randomly chosen two-digit whole numbers is one of theses these possibilities is thus 48/8100 = 4/675.

During a business trip, an individual stopped at two rest stops. In the parking lot of the first rest stop, they counted 20 cars

olganol [36]

Answer

given,

on first stop

number of car = 20 and number of trucks = 18

on second stop

number of car = 18 and number of trucks = 10

we need to calculate which rest stop has higher ratio of car to truck.

Rest Stop 1
