5. A system of equations is below. For what value would
you multiply the first equation to eliminate the x-term?
(y=x+2
3x + 3y = 6
Answer:
We would multiply the first equation by -3 to eliminate the x-term.
Step-by-step explanation:
Given the system of equations
y = x+2 Equation 1
3x+3y = 6 Equation 2
Multiply the Equation 1 by -3
-3y = -3(x+2) ⇒ -3y = -3x-6 ⇒ -3x+3y = 6
Thus, equation 1 becomes
-3x+3y = 6
Now, adding equation 2
-3x+3y = 6
+
3x+3y = 6
________
0x + 6y = 12
6y = 12
y = 2
Therefore, we would multiply the first equation by -3 to eliminate the x-term.

What is a solution set for 3t-5>7?
Step-by-step explanation:
3t - 5 > 7
3t > 12 (add 5 to both sides)
t > 4 (divide 3 on both sides)
The solution set for t should only have values which are greater than 4.
Hence the answer is C.

Answer:
150 degrees
Step-by-step explanation:
The sum of all angles in a pentagon is 540 degrees. So you add the measurements of the 4 you know - 95 + 95 + 100 + 100 = 390. Then you subtract 540 - 390 - 150 degrees for the last angle.

What are 2 different equivalent fractions for LaTeX: \frac{2}{6}2 6 ? *In your answer, use a "/" as a fraction bar symbol. For example, LaTeX: \frac{2}{6}2 6 can be typed as 2/6
Answer:
4/12 and 6/18
Step-by-step explanation:
Given the fraction 2/6
We are to write 2 different equivalent fractions that are the same as 2/6
To do this, we will multiply the numerator and denominator of the fraction by same constant. Multiply the numerator and denominator by 2 will give;
2/6 * 2/2
= (2*2)/(6*2)
= 4/12
Also multiplying by a value of 3
= 2/6 * 3/3
= (2*3)/(6*3)
= 6/18
Hence the 2 different equivalent fractions are 4/12 and 6/18

A 36 ft tree casts a 9 ft shadow at the same time a building casts a 15 ft shadow. How tall is the building?
Answer: The height of the tree is 27f t
Step-by-step explanation: We can set up a proportion comparing the height of each object to the length of the shadow.
h/s
h/15=18/10
Cross multiply
10.h= 18*15
10h=270
Use the multiplicative Inverse
10 h/ 10 = 270 /10 =27

going up by 3 for the cup cakes and goimg by 1 forthe cookies
Answer:
The last option
Step-by-step explanation:
it's because when you say 3 times as many it means
if we have x ----> 3 times as many is 3x
and it doesn't work in any case
so we have the last two options
option H means that the number of cupcakes is less than the number of cookies which is not true
so the only one is the last option

The value of Cos(60°) is ½
Step-by-step explanation:
B)as we know
b²=a²+c²-2ac.cos(b)
b=√5²+8²-2.5.8×cos(60°)
b=√25+64-80×½
b=√25+64-40
b=√89-40
b=√49
