Solve for x using cross multiplication 3x - 3 5 = 2x – 2 4 x = [?]
Answer:
x = -35/22, or 1.5909090...
Step-by-step explanation:
Solving for x will be easy enough, but cross multiplication won't be necessary as that's only applicable when division is involved:
35 = 2x - 24x
35 = -22x
x = -35/22, or 1.5909090...
does anyone know how to solve this? I have to find lengths FJ, DM, and EM
Answer:
FJ= 24
DM= 16
EM= 18
Step-by-step explanation:
The centroid is twice as close along any median to the side that the median intersects as it is to the vertex it emanates from.
So in the case of FJ, the median intersects the side at point J and extends from vertex F. This means that FM is twice as long as MJ. It tells us that MJ is 8, so MF would be 16. Now because FJ is just FM+MJ, FJ is 24.
It also tells us that DK is 24, which means that DM+MK = 24. If DM is twice as long as MK, that would make MK equal to 8 and DM equal to 16
Similarily, EM would be twice as long as ML. It says that ML=9 so that would make EM=18
These are numbers that cannot be written as fractions, numbers with decimals that do not end or repeat. Example: π, 2.345643.....,

. 3^2x+1 = 1 solve it
Answer:
x= 0
Step-by-step explanation:
name the property that justifies each statement -3(m+8)=-3m-24
Answer: Distributive Property
Explanation: The distributive property tells us that if we're given an expression such as -3(m + 8), we can multiply the -3 by both the m and the 8.

Nutritionists measured the sugar content (in grams) for 32 drinks at Jake's Java
coffee shop. The drinks had a mean sugar content of 18g and a standard
deviation of 5g, and the distribution was roughly symmetric.
Question 1: Grande Mocha Cappuccino at Jake's Java contains 14 g of sugar.
Calculate the standardized score (z-score) for the Grande Mocha Cappuccino.
Answer:
[tex]z = -0.8[/tex]
Step-by-step explanation:
Given
[tex]n = 32[/tex] --- samples
[tex]\mu = 18g[/tex] --- mean
[tex]\sigma =5g[/tex] --- standard deviation
[tex]x = 14g[/tex] --- observed value
Required
Find the standardized score
This is calculated as:
[tex]z = \frac{x - \mu}{\sigma}[/tex]
So:
[tex]z = \frac{14g -18g}{5g}[/tex]
[tex]z = \frac{-4g}{5g}[/tex]
[tex]z = \frac{-4}{5}[/tex]
[tex]z = -0.8[/tex]
The standardized score is -0.8

Answer:
x = -4
Step-by-step explanation:
x= 3 is a parallel to y axis. So a parallel line to x = 3 must be parallel to y axis.
A line parallel to y axis has a generic equation: x = h. We know that the line passes to the point with has x coordinate = -4
So the equation is x= -4

This question is asking us to find the sum of [tex]4(3)^{n-1}[/tex] from n = 1 to n = 6. We can find the sum like this:
[tex]4(3)^{1-1} +4(3)^{2-1} +4(3)^{3-1} +4(3)^{4-1} +4(3)^{5-1} +4(3)^{6-1}[/tex]
Which can be simplified to:
[tex]4(3)^{0} +4(3)^{1} +4(3)^{2} +4(3)^{3} +4(3)^{4} +4(3)^{5}[/tex]
[tex]4(1) +4(3) +4(9) +4(27)+4(81) +4(243)[/tex]
[tex]4 +12 +36 +108+324 +972 = 1456[/tex]

Is 12+5(2+y) and 5y+22 equivalent
Answer:
22 + 5y
Step-by-step explanation:
Yes they are
5 x 2 = 10 + 5 x y = 5y, 10 + 12 = 22, therefore you get 22 + 5y.
5. How much force is needed to stop a 1,400 kg truck pulling up to a stop light if
the truck took 4 seconds to stop and was moving at 36 m/s?
Answer:
Step-by-step explanation:
F=ma
F=m(dv/dt)
F=1400(-36/4)
F=-12600N (the negative sign just means the force was slowing the vehicle, the magnitude of the force is just the absolute value.
F=12600N

What is the perimeter and area of the composite figure?
Step-by-step explanation:
▪AB = AC - EF
= 13 cm - 7 cm
= 6 cm
▪BD = CF - DE
= 16 - 8 cm
= 8 cm
BC = EF
perimeter = CF + EF + DE + AD + AB + BC
= 16 + 7 + 8 + 10 + 6 + 7
= 54 cm
Area of triangles = 1/2 × AB × BD
= 1/2 × 6 × 8
= 48/2
= 24 cm²
Area of rectangle = CF × EF
= 16 × 7
= 112 cm²
the total area = 24 + 112
= 136 cm²

True or false?is the point(16,4) included in this function: Y=2x or Y=x2 or y= x+12 or y=x-12
Answer:
True
Step-by-step explanation:
It is true because the graph of [tex]y=x-12[/tex] passes through the point [tex](16,4)[/tex]
x = 16
y = 4
Substitute
4 = 16 - 12
4 = 4
Therefore, the answer is true.
