Your answers are :

A=E    5x2=10+7=17 so 17=17
B=G     3x-2=-6+1=-5 so -5=-5
C=F    2x1=2+1=3 so 3=3
D=H     3x-2=-6. 5-(-6)=5+6=11 so 11=11

Answer: A-> E; B->G; C->F; D->H

Step-by-step explanation:

For the first inequality;

5x+7>=17

5x>=17-7

5x>=10

x>=2 (The equivalent number line will be E)

For the second inequality;

1+3x>=-5

3x>=-5-1

3x>=-6

x>=-2 (The equivalent number line will be G)

For the inequality

2x+1<=3

2x<=3-1

2x<=2

x<=1 (The equivalent number line will be F)

frozen [14]

Answer:

10%

Step-by-step explanation:

To find the percentage, ask yourself, how much is 2000 of the original value which is 20350.   This can be solved by the following equation.

2000/20350=

The answer is approximately 0.09828.   Then, convert this to a percent. 9.828%. Then, round it to the nearest percent. The answer is 10%

Solve the following triangle. Given A=51 degrees b=40 c=45
STALIN [3.7K]

Answer:

a=36.87\ units

B=57.47^o

C=71.53^o

Step-by-step explanation:

step 1

Find the length side a

Applying the law of cosines

a^2=b^2+c^2-2(b)(c)cos(A)

substitute the given values

a^2=40^2+45^2-2(40)(45)cos(51^o)

a^2=1,359.4466

a=36.87\ units

step 2

Find the measure of angle B

Applying the law of sines

\frac{a}{sin(A)} =\frac{b}{sin(B)}

substitute the given values

\frac{36.87}{sin(51^o)} =\frac{40}{sin(B)}

sin(B)=\frac{sin(51^o)}{36.87}{40}

B=sin^{-1}(\frac{sin(51^o)}{36.87}{40})=57.47^o

step 3

Find the measure of angle C

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

so

A+B+C=180^o

substitute the given values

51^o+57.47^o+C=180^o

108.47^o+C=180^o

C=180^o-108.47^o=71.53^o
