1) x= -7
2) x= -5
3) x=-22
4) x =8
Not sure about the last one tho
I tried to help :)
Answer:
The first one is a line because a line extends infinitely in both directions which the arrows indicate.
The second one is a plane since it is a 2-dimensional shape.
The last one depicts 2 rays because rays have one endpoint, but extend infinitely in the other direction.
The last two options are correct, but it looks like you’ve got them :)
Let assume that the the two numbers are X and Y and that X is the large number.
According to the question,
X + Y = 53 .................. Equation 1
then, X = 11 + Y........... Equation 2
Substitute equation 2 into equation 1.
[11 + Y] + Y = 53
11 + 2Y = 53
2Y = 53 - 11 = 42
2Y = 42
Y = 42 / 2 = 21,
Therefore, Y = 21 [Small number].
According to equation 1,
X +Y = 53
X + 21 = 53
X = 53 - 21 = 32.
Therefore, X = 32 [Big number].
Answer:
57:38
Step-by-step explanation:
3/2(19):x
3:2
3x = 2 * 3/2 * 19
3x = 57
x = 19
Since the ratio is 3:2, then the scores at half-time were 57:38
