What is the value of x in the y = 2/3x + 5 when y=7?
Answers
Answer:
x = 3
Step-by-step explanation:
y = 2/3 x + 5; y = 7
7 = (2/3)x + 5
2 = (2/3)x
x = 2 * 3/2
x = 3
Answer:
x=3
Step-by-step explanation:
To start all you need to do is replace [tex]y[/tex] with 7 to get [tex]7=\frac{2}{3}x+5[/tex]
Then, you need to isolate x on the right side of the equation, starting with subtracting 5 on both sides to get [tex]2=\frac{2}{3}x[/tex]
Finally, you divide both sides by [tex]\frac{2}{3}[/tex]. You divide fractions by multiplying the reciprocal like so [tex]\frac{2}{1} *\frac{3}{2} =x[/tex] to get [tex]\frac{6}{2} =x[/tex]. This means that x=3
Which expression is equivalent to 6a + 15?
6(a + 5)
3(2a + 5)
3(3a + 12)
6(a + 12)
Answers
Explanation:
6(a+b) = 6a +30 (it is not equivalent to 6a+15)
You have to multiply what’s in the brackets by 6
3(2a+5) = 6a+15 ( it is equivalent )
3 (3a+12) = 9a+36 (not equivalent)
6(a+12) = 6a+12 (not equivalent)

If X is the lost value, and if we know that X was the middle value of the five days, which choice could be the value of X? A) −1.9 °C B) −0.9 °C C) −0.1 °C D) 0.4 °C
Answers
Answer: D
Step-by-step explanation:
If you notice there is a pattern going on here the first temp recorded is negetive then the next is a normal temp then the next is negetive so it would be reasonable to think that the next temp would be normal and all the other options are negetive exept for one which is D so the answer is D.

What are the values of x and y?
a) 3x + 5y = 26
b) 2x + 2y = 12
Step One: We need to find a way to equate either the x terms of the y terms in each equation. Multiply equation a) by 2 and equation b) by 3 to form the following equations.
a) 6x + 10y = 52
b) 6x + 6y = 36
Step Two: Take equation b) from equation a) to eliminate the x component.
a) 6x + 10y = 52
- b) 6x + 6y = 36
0x + 4y = 16
y = 4
Step Three: substitute the value of y into either equation to find the value of x.
b) 2x + 2y = 12
2x + (2x4) =12
2x + 8 = 12
2x = 4
x = 2
x=2 y=4

What is the minimum angle of rotation (in degrees) that will carry the six-sided star onto itself?
Answers
Answer:
The angle of rotation pf a six sided star, that will carry the six sided star onto itself is 60°
Step-by-step explanation:
The angle of rotation that will carry a six sided star onto itself is the angle between two adjacent lines of symmetry of the six sided star
Given that there are three lines of symmetry of the six sided star, and each line intersect with the next line at the center of the figure, the angle between two adjacent lines of symmetry = 360°/(2 × 3) = 60°
Therefore, the angle of rotation pf a six sided star, that will carry the six sided star onto itself = 60°.

Jack's birthday is in 8 weeks. How many days is it until Jack's birthday? Complete the explanation on how you could use a number line to solve. Jack's birthday is in days. I would draw equal jumps of beginning at 0 on the number line. The jumps end at .
Answers
Answer:
Jack's birthday is in 56 days.
The jumps end at point 56 on the number line.
Step-by-step explanation:
Since one week has 7 days.
So, 8 week = 8 x 7 =56 days.
Hence, Jack's birthday is in 56 days.
On the number line, the current time is being represented by 0.
When I take one jump from 0, I will reach the point 1 on the number line, which corresponds to 1 day.
Again, in my 2nd jump from point 1 on the number line, the next point on the number line will be 2 which corresponds to 2 days.
This process repeats until I complete the 56 jumps to get point 56 on the number line, which corresponds to 56 days.
In this way, the number line can be used to solve.
Hence, the jumps end at point 56 on the number line.

Step-by-step explanation:
We know that 4x + 3 < 5 and 4x + 3 > -5
4x + 3 < 5
~Subtract 3 to both sides
4x < 2
~Divide 4 to both sides
x < 2/4 or x < 1/2
4x + 3 > -5
~Subtract 3 to both sides
4x > -8
~Divide 4 to both sides
x > -2
