Answer:
35+5x
Step-by-step explanation:
Pick each bracket and solve them separately. After solving, then you add them
the first bracket= (9x2-2x+7) = 25-2x ------- eqn 1
the second bracket= (4x2+7x+2) = 10+7x ---- eqn 2
Add eqn 1 and 2
= (25-2x) + (10+7x)
Grouping like terms,
= (25+10) + (-2x+7x)
=35+5x
Answer:
The expression is C/20 cups of flour in one cake
Step-by-step explanation:
* Lets explain how to solve the problem
- There are 10 students
- Each one made 2 chocolate cakes
- They all used the same recipe
- The total amount of flour is C cups
* Lets change these information to equation
∵ There are 10 students
∵ Each student made 2 cakes
∴ The total number of cakes = 10 × 2 = 20 cakes
∵ The total amount of flour for the twenty cakes is C cups
- To find the amount of flour in each cake divide the total amount
of flour by the total number of the cakes
∴ The amount of flour in each cake = C/20
* The expression is C/20 cups of flour in one cake
Mars is 2×10⁸/6×10⁷=20×10⁷/6×10⁷=20/6=10/3=3.3 times farther from the sun than Mercury.
