Answer:
CD = 11 unitsStep-by-step explanation:
See the drawing attached
GivenC is midpoint of ABB is between A and DAD = 15BD = 7Find CDSolutionCD = CB + BD = 1/2AB + BD = 1/2(AD - BD) + BD =1/2(15 - 7) + 7 =1/2(8) + 7 =4 + 7 =11-x+y = 5
x - 5y = -9
Solve by elimination
Y and x
Answer:
x = -4 and y = 1
Step-by-step explanation:
-x + y = 5
+ x - 5y = -9 <— let’s eliminate x
————————————-
-4y = -4
y = 1
x - 5y = -9 <— substitute for y
x - 5(1) = -9
x - 5 = -9
+5 = +5
x = -4

evaluate 7y-3y for y=2
Answer:
8
Step-by-step explanation:
So. Let's plug in 2 for y. 7(2)-3(2). Before we subtract, let's multiply first. 7 times 2 is 14 and 3 times 2 is 6. So now the equation looks like this: 14-6. From here, you do regular subtraction to get 8. Hope this helps!

where does x go in the fraction?
15/100 = ?/?
3 left parenthesis x space minus space 8 right parenthesis greater than negative 4 space plus space x
Answer:
The solution of the given inequality
x > 10
Step-by-step explanation:
Step(i):-
Given inequality
3 ( x-8) > -4 + x
Multiply
3 x - 24 > -4 +x
subtract 'x' on both sides , we get
3 x - 24 - x > - 4 + x - x
⇒ 2 x - 24 > - 4
Step(ii):-
Adding '2'4' on both sides , we get
⇒ 2x - 24 + 24 > -4 +24
⇒ 2 x > 20
Dividing '2' on both sides , we get
[tex]\frac{2x}{2} > \frac{20}{2}[/tex]
x > 10
Final answer:-
The solution of the given inequality
x > 10

Express 49 1/2 in simplest radical form.
Answer:
[tex]\sqrt{49}[/tex]=7
The value of the square root of the number 49 is 7.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs. An nth root of a number x is a number r that when raised to the power n yields x.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the number is 49 and the square of the number is calculated as,
E = √49
E = √ ( 7 x 7 )
E = 7

Answer:Solve x=−5−y;2+y=−x+3
I will solve your system by substitution.
x=−y−5;y+2=−x+3
Step: Solvex=−y−5for x:
Step: Substitute−y−5forxiny+2=−x+3:
y+2=−x+3
y+2=−(−y−5)+3
y+2=y+8(Simplify both sides of the equation)
y+2+−y=y+8+−y(Add -y to both sides)
2=8

Answer:
7x = 35cm ; 2x = 10cm
Step-by-step explanation:
7x and 2x are the lengths
7x+2x=45
Then you take 7 + 2 = 9
so is gonna be 9x = 45
then you divide both side with 9
so is gonna be x = 5
Then you take 5 multiply 7 : 2
so 7 x 5 = 35cm
2 x 5 = 10cm

Forty students went on a trip on Wednesday. On Thursday, 15% less students went on a similar trip. How many students went on the trip on Thursday?
Answer:
34
Step-by-step explanation:
40 * .15= 6
40-6 = 34
okkk so you do 40 * .15 because you just put a decimal point before all percentages to convert it into number
40*.15= 6
then subtract 6 to the original amount
40-6=34
34 students went on the trip on thursday cause 6 students got killed by bears in the last trip.

Answer: Hi, the answer is 9/4 or C!
Step-by-step explanation:
You would take 2/7 and multiply both the top and bottom by 2 to make it 4/14, the. youd flip 4/14 into 14/4, then multiply the top numbers (9 and 14 by eachother to get 126) then multiply the bottom numbers ( 14 and 4 to get 56) and simplify the new fraction (126/56) to get 9/4!

Find t:
0.70t = 35. Dividing both sides by 0.70, we get:
35
t = ----------- = 50
0.70
The total trip length is 50 miles.
Please help me- AND PLEASE EXPLAIN
Answer:
A=35, B=55, and C=25
Step-by-step explanation:
Angle A and the angle next to it are linear pairs, so you can subtract 145 from 180.
if you already know Angle A, and that the other angle is 90 degress, you can add 90+35 and subtract it from 180 to get Angle B
Angle C is paired with the angle across from it (I forgot what the term is called) so it is 25 degrees.
