Answer:

2.5 x 13.7 = 34.25

4.9 + 1.6 = 6.5

Step-by-step explanation:

Here we are multiplying 2 decimals we can just write it as

25 * 10^{-1} * 137 * 10^{-1}

= 25*137*10^{-2}

= 3425 *10^{-2}

= 34.25

Here we are just performing simple addition

4.9 + 1.6

= 49 *10^{-1} +16*10^{-1}

= (49+16)*10^{-1}

=65 * 10^{-1}

= 6.5

Gideon took an online math test consisting of 25
kondor19780726 [428]

Step-by-step explanation:

25 questions, 2 points each.

that means there were 25×2 = 50 points in total.

Gideon got 42 out of the 50.

100% = 50

1% = 100%/100 = 50/100 = 0.5

42 is how many % ? as many as 1% (0.5) fits into 42.

so,

42/0.5 = 42×2 = 84%

he scored 84%.

Find the value of x. Then find the angle measures of the polygon.
Bess [88]

Question 11

x+x+1/2x+1/2x=360

x+x+2/2x+=360

x+x+x=360

3x=360

x=120

Then substitute 120 in the place of x

x1=120

x2=120

1/2(120)=60

1/2(120)=60

To check your answer you can add 60+60+120+120 the should be equal to 360

Question 12

x+x+(x-45)+(x-45)+(x-45)=540

x+x+x-45+x-45+x-45=540

5x-135=540

5x=540+135

5x=675

x=675/5

x=135

Then substitute 135 in the place of x

x1=135

x2=135

135-45=90

135-45=90

135-45=90

To check your answer you can add 135+135+90+90-90 the should be equal to 540

Hope it helps
