Answer:

Do you really mean by -9 or cause I'm just confused but if you meant by 19 then this could help. I had my mom do whatever she could put as the answer so yeah

Step-by-step explanation:

a*b=18 ____[1]

a+b=19____[2]

[2] a=19-b ___[3]

put [3] in [1]

(19-b)*b = 18

19b-b^2 = 18

b^2-19b+18 = 0

(b-18)(b-1) = 0

so b=18 or b=1

if b=18 then a=19-18=1

if b=1 then a=19-1=18

SO two factors are 1 and 18

What is the value of angle v?

Flauer [41]

Answer:

x = 5

Step-by-step explanation:

a) The third interior angle of this triangle is 180 - 20 x.

The three interior angles must sum up to 180 degrees.

Therefore, 60 + 7x + 5 + 180 - 20x = 180, or

65 + 180 - 13x = 180, or

65 - 13x = 0

Finally, 13x = 65, and so x = 5

Answer:

A x=1/4

Step-by-step explanation:

2/3x = 1/6

Divide by 2/3

so 1/6 ÷ 2/3

= 1/6 • 3/2

= 3/12

A supplier sells 2 and 1/4 pounds of mulch for every 1 and 1/3 pounds of gravel. The supplier sells 172 pounds of mulch and grav

polet [3.4K]

Because ratios can be written as fractions
$\frac{mulch}{2.25}=\frac{gravel}{1.33}$

172 = $\frac{mulch}{2.25}+ \frac{gravel}{1.33}$
172 - $\frac{mulch}{2.25}$ = $\frac{gravel}{1.33}$
76.44 mulch = x amount of gravel = 172
Gravel = 172 - 76.44
= 95.56

What is the value of x in 145.95-2x=-4.05?

kotykmax [81]

145.95 - 2x = -4.05
subtract -145.95 from both side of the equation
-2x = -4.05 - 145.95
-2x = -150
Divide both sides by -2
-2x/2 = -150/2

x = 75
Final answer

Hope this helps!!!!

Triangle J is shown below. James drew a scaled version of Triangle J using a scale factor of 4 and labeled it

Novay_Z [31]

Answer:

The area of triangle K is 16 times greater than the area of triangle J

Step-by-step explanation:

we know that

If Triangle K is a scaled version of Triangle J

then

Triangle K and Triangle J are similar

If two triangles are similar, then the ratio of its areas is equal to the scale factor squared
