The answer is C. 6+3 x (-5)
Answer:
A = 3 units^2
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the length of the base and h is the height
b = the distance from B to C = 4 units = 2 ( watch the scale)
h = the distance from A to C along the x axis =6 units = 3 (watch the scale)
A = 1/2 (2)(3)
A = 3 units^2
Answer
Find out the how much did the height of the tree sapling increases.
To proof
Let us assume that the height of the tree sapling increases be x.
As given
The high every tree sapling was 3.15 inches last year
this year the high is 5.38 inches.
than the equation is become in the form
x = 5.38 - 3.15
x = 2.23 inches
Therefore the height of the tree sapling increases be 2.23 inches.
Hence proved
By solving a linear equation, we will see that Victor is 30 years old.
<h3>
How old is Victor now?</h3>
Let's say that Victor is x years old.
We know that 10 years ago, (x - 10), his age was half of what it will be in 10 years (x + 10).
Then we can write the linear equation:
(x - 10) = (x + 10)/2
Now we can solve that equation for x:
2*(x - 10) = x + 10
2x - 20 = x + 10
2x - x = 10 + 20
x = 30
So we conclude that Victor is 30 years old.

Answer:
Recipe for a cup of lentils = 6 scoops
Recipes for a salad = 12 scoops
Step-by-step explanation:
Hannah is cooking enough lentils for lentil soup and a lentil salad. The soup recipe calls for ¾ cup of lentils. The salad recipe calls for 1 ½ cups of lentils. But Hannah only has a ⅛ measuring scoop.
How many scoops of lentils will Hannah need for both recipes?
a) Recipe for a cup of lentils
The soup recipe calls for ¾ cup of lentils.
Hannah only has a ⅛ measuring scoop.
Hence,
3/4 ÷ 1/8
= 3/4 × 8/1
= 6 scoops
Recipes for a salad
The salad recipe calls for 1 ½ cups of lentils.
Hannah only has a ⅛ measuring scoop.
Hence,
1 1/2 ÷ 1/8
= 3/2 ÷ 1/8
= 3/2 × 8/1
= 12 scoops
