Answer:
TW = ST
Step-by-step explanation:
RS = RW (Given)
RT = RT (reflexive property)
This makes ∆RST congruent to ∆RWT based on the reflexive property of congruence.
Therefore, the third corresponding sides, TW and ST would be congruent to each other.
Thus:
TW = ST
Answer:
B (5, 13)
Step-by-step explanation:
9x + 4y = 97
9x + 6y = 123
To solve by elimination, we want to <em>eliminate</em> a variable. To do this, we must make one variable cancel out.
First, we can see that both equations have 9x. To cancel out x, we must make <em>one</em> of the 9x's <em>negative</em>. To do this, multiply <em>each term</em> in the equation by -1.
-1(9x + 6y = 123)
-9x - 6y = -123
This is one of your equations. Set it up with your other given equation.
9x + 4y = 97
-9x - 6y = -123
Imagine this is one equation. Since every term is negative, you will be subtracting each term.
9x + 4y = 97
-9x - 6y = -123
___________
0x -2y = -26
-2y = -26
To isolate y further, divide both sides by -2.
y = 13
Now, to find x, plug y back into one of the original equations.
9x + 4(13) = 97
Multiply.
9x + 52 = 97
Subtract.
9x = 45
Divide.
x = 5
Check your answer by plugging both variables into the equation you have not used yet.
-9(5) - 6(13) = -123
-45 - 78 = -123
-123 = -123
Your answer is correct!

Answer:
?=14
Step-by-step explanation:
12+5=17
8+8=16
8+4х8=40
4+6х4=28
9-5=4
9-12+5+8+4=14
I need the following...
4y+24 would be the answer
--v---v
4(y+6) ... To get rid of parenthesis, simply multiply 4 by y, and 4 by 6.
4y+24 is the answer.
Answer:
7 9/10
Step-by-step explanation:
First, we need to add 4 2/3 and 5 2/5.
We should begin with converting the fractions into improper fractions.
4 2/3 + 5 2/5= 14/3 + 27/5
Now, we find the common denominator
= 70/15 + 71/15
We can add:
= 141/15
And simplify.
= 9 2/5
Finally, we subtract 1 1/2 from 9 2/5
Your answer is 7 9/10. Hope this helps!
