Answer:

29

Step-by-step explanation:

since her age is 3 more than twice her brothers age we'll subtract 3

42 - 3 = 39

since shes twice her brothers age theres actually 3 numbers. her brother's age which is the base number, and her age, which is is that times 2. so in order to get her brothers age we divide by 3

39 ÷ 3 = 13

since shes twice his age + 3 we'll multiply by 2, then add 3

13 × 2 + 3 = 29

I hope this isnt too complicated! I tried to simplify it but I think it came out more confusing than I intended

Britta bought some carrots and apples for $24.80. A carrot and an apple cost .90 cents all together. She bought more carrots tha
MrRissso [65]

Answer:

20

Step-by-step explanation:

24.80-6.80=$18   that's what Britta spent on equal number of carrots and apples because $6.80 was spent on extra carrots only.

18/ .90=20 that means she got 20 apples and 20 carrots before she added $6.80 to buy some extra carrots

Thus, the number of apples Britta bought = 20

With the beam being held still at a height of 40 m, the crane breaks and the beam falls to the ground. Assuming no air resistanc
lapo4ka [179]
What we have so far:
Kinetic energy = 0. The reason behind that is because the beam is not moving at a height of 40m.
Gavity, g = 9.8m/s²
Height = 40m
Potential energy = mgh; this is equal to 0 because m, stands for mass and in this problem, we do not have a value for the mass of the beam. Hence, 0 x 9.8m/s² x 40m = 0. Potential energy = 0.

Solution:
We will use the equation of Total energy:
TE = potential energy + kinetic energy

TE = 0 + 0

∴ TE = 0

The answer is: Assuming no air resistance, the total energy of the beam as it hits the ground is 0.

Find the slope-intercept form of the lines with the following properties.
Vikentia [17]

Hello!

If you want to find an equation that is parallel to another equation, and passing through the point (1, 4), you need to create a new equation with the same slope, you need to substitute the given point into the new equation to find the y-intercept.

m = 3, y = 3x + b (substitute the ordered pair)

4 = 3(1) + b (simplify)

4 = 3 + b (subtract 3 from both sides)

b = 1

Therefore, the line parallel to the line y = 3x - 2 and passing through the point (1, 4) is y = 3x + 1.
