Step-by-step explanation:
[tex]In\: \triangle CDE\\\\
m\angle C + m\angle D + m\angle E = 180\degree \\\\
48\degree + 74\degree + m\angle E = 180\degree \\\\
122\degree + m\angle E = 180\degree \\\\
m\angle E = 180\degree- 122\degree \\\\
\huge \red {m\angle E = 58\degree} \\\\
\because \triangle ABC \cong \triangle DEC... (given) \\\\
\therefore \angle B \cong \angle E.. (CACT) \\\\
\therefore m\angle B = m\angle E\\\\

3x -10+ 4x= -2 (x-4) +9
Answers
Answer:
x = 3
Step-by-step explanation:
Step 1: Write equation
3x - 10 + 4x = -2(x - 4) + 9
Step 2: Solve for x
Distribute -2: 3x - 10 + 4x = -2x + 8 + 9Combine like terms: 7x - 10 = -2x + 17Add 2x to both sides: 9x - 10 = 17Add 10 to both sides: 9x = 27Divide both sides by 9: x = 3Step 3: Check
Plug in x to verify it's a solution.
3(3) - 10 + 4(3) = -2(3 - 4) + 9
9 - 10 + 12 = -2(-1) + 9
-1 + 12 = 2 + 9
11 = 11
7x-10=-2x+8+9
7x-10=-2x+17
7x+2x=17+10
9x=27
x=3
You have $70 in your bank account. Each week you plan to deposit $7 from your allowance and $10 from your paycheck. The equation b = 70 + (10 + 7)w gives the amount b in your account after w weeks. How many weeks from now will you have $185 in your bank account?
Answers
Answer:
After 7 weeks from now you will have $185 in your bank account.
Step-by-step explanation:
We are given that you have $70 in your bank account. Each week you plan to deposit $7 from your allowance and $10 from your paycheck. The equation b = 70 + (10 + 7)w gives the amount b in your account after w weeks.
The equation is given by;
b = 70 + (10 + 7)w
Now, in the question, it is given that you have $185 in your bank account, that means;
$185 = $70 + $17w
Finding the value of w(weeks);
$17w = $185 - $70
$17w = $115
w = [tex]\frac{\$115}{\$17}[/tex]
w = 6.76 weeks or 7 weeks (approx).
Hence, after 7 weeks from now you will have $185 in your bank account.
Jenny is solving the equation 3 x + 5 = 4 x + 2 using algebra tiles. She cannot decide if she should add 3 negative x-tiles or add 2 negative unit tiles to both sides first. Which explains which Jenny should do first?
A.She should add 3 negative x-tiles first because that is the only way to isolate the variable.
B.She should add 2 negative unit tiles first because that is the only way to get to the correct solution.
C.She can do either one first because zero pairs will be created to isolate the variable either way.
D.She should do neither one first because the first step is to add 4 negative tiles to both sides.

Please help on this: Given: 4c-d = f, d = c-e, f = d + e; Prove: 3c = d
Answers
Answer:
Step-by-step explanation:
Given the equations:
4c-d = f ....... 1
d = c-e....... 2
f = d + e....... 3
Substitute 2 into 1
4c -(c-e) = f
4c -c + e =f
3c + e = f ......4
Substitute equation 3 into 4:
3c+e = d+e
subtract e from both sides
3c+e-e = d+e-e
3c = c (Proved)

The prime factorization of a number is . Which statement is true about the factors of the number? Twenty-one is a factor of the number because both 3 and 7 are prime factors. Twenty-one is not a factor of the number because 21 is not prime. Ninety is a factor of the number because and 90 is divisible by 9. Ninety is not a factor of the number because 90 is not divisible by 7.
Answers
Answer & Step-by-step explanation:
Factors of a number are the number(s) whose product ie multiplication gives the number. Prime factorisation is finding 'prime' factors of numbers, ie the numbers which dont have a factor further - other than themselves & 1.
Example : 6 = 2 x 3, so 2 & 3 are factors of 6. Also, 2 & 3 are prime factors, as they dont have further multiplication factors, other than themselves (2 & 3 respectively) & 1. So this can be an illustrative case of prime factorisation of 6.
Answer:
Answer:
Twenty-one is a factor of the number because both 3 and 7 are prime factors.
Step-by-step explanation:
Given number is,
3^2\times 5^3\times 73
2
×5
3
×7
=3\times 3\times 5\times 5\times 5\times 7=3×3×5×5×5×7
Where, 3, 5 and 7 are prime numbers ( only divisible by 1 and itself ),
⇒ Both 3 and 7 are prime factors of the given number,
⇒ 21 is a factor of the given number.
Thus, first option is correct.
⇒ Second option is incorrect.
Now, 5 is factor of the given number but 2 is not,
⇒ 10 is not a factor of the given number,
⇒ 90 is not a factor of the given number,
⇒ Third option is incorrect.
Suppose 90 is divisible by 7,
⇒ 90 = 7a
Where a is any whole number,
⇒ 7=\frac{90}{a}7=
a
90
3^2\times 5^3\times 7=3^2\times 5^3\times \frac{90}{a}3
2
×5
3
×7=3
2
×5
3
×
a
90
Since, 90 could be a factor of this number, if a = 3 or 5 or their multiple,
For the other values of a, 90 can not be the factor,
Hence, there is no effect of divisibility of 90 by 7 on having 90 as a factor of the given number,
⇒ Fourth option is incorrect.
