Answer:
4y + (y − 1) = 29
(2y + 3) − 4 = 9
4y − y + 1 = 13
Step-by-step explanation:
We will have to check each equation for the given values of y.
So,
1. (2y + 3) − 4 = 9
For y=4
[2(4)+3]-4=9
(8+3)-4=9
11-4=9
7=9
Not true for 4
For y=5
[2(5)+3]-4=9
(10+3)-4=9
13-4=9
9=9
True for 5
2. 4y − y + 1 = 13
For y=4
4(4)-4+1=13
16-4+1=13
13=13
True for 4
3. 4y + (y − 1) = 29
As we have already used 4 and 5 we will check for 6 and onwards
For y=6
6(4)+(6-1)=29
24+5=29
29=29
So the equations in decresing order of y that make them true are:
4y + (y − 1) = 29
(2y + 3) − 4 = 9
4y − y + 1 = 13 ..
C. an irrational number cannot be a whole number, an integer, a fraction, or a decimal
Answer:
Step-by-step explanation:
here ,
6x +238 = 3x+178 ( vertically opposite angles are equal)
so 6x - 3x = 178 -238
3x =-60
x =-60/3
x=-20
hope it helps / please mark me as the brainliest..
Mrs. Smythe = x
Daughter = y
x = 2y
(x - 10) + (y - 10) = 46
x - 10 + y - 10 = 46
x + y - 20 = 46
x + y = 66
Put 2y in for x
2y + y = 66
3y = 66
y = 66/3
y = 22
The daughter is 22
The mother = 44
Answer:
The correct answer is 1/49
Step-by-step explanation:
In order to find this, we first can eliminate the negative in the exponent by putting the whole this in the denominator.
(-7)^-2 = 1/(-7)^2
Now we can evaluate the denominator
1/(-7)^2 = 1/49
