Answer:
62r+9
Step-by-step explanation:
Let's simplify step-by-step.
8r+7−6r−58r+7−6r−5
=8r+7+−6r+−58r+7+−6r+−5
Combine Like Terms:
=8r+7+−6r+−58r+7+−6r+−5
=(8r+−6r+−58r+−6r)+(7+7+−5)
=−62r+9
Answer:
=−62r+9

Answer: 5
Step-by-step explanation:
.
This is fairly simple, you just have to know how to set up an equation like this. It says that the package weighs 2340 grams. The item removed weights 700 grams. You just have to subtract these values to get the new weight of the package. 2340-700=1640
Answer:
1)B:63°
2)A:59°
Step-by-step explanation:
1.ABC is a right triangle at C then angle ACB=90°(right angle)
Angle CAB=27°(see the given)
measure of the angles in any triangle is 180°
then angle CBA=
measure of all the angles - (measure ACB+measure CAB)
=180°-(90°+27°)
=63°
2. Same explanation of angle B:
in the right triangle DEF: angle DEF=90°
angle D=31°(given)
Then measure of angle A=180°-(angle E + angle D)
=180-(90+31)=59°
