Answer:
2a + 3b = 0
Step-by-step explanation:
So we are given that a = -3, b = 2, c = 5, and d = -4 and we are asked to evaluate the expression 2a + 3b. To evaluate the expression, we would have to plug in -3 for a, 2 for b, 5 for c, and -4 for d:
2a + 3b = 2(-3) + 3(2) = -6 + 6 = 0
So by evaluating the expression we get 0.

What is arithmetic sequence?An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.
Given the nth term of a sequence to be b(n)=b(n-1)+1, where n is the number of terms of the sequence
If b(1) = 16... (1)
The second term of the sequence is generated for n= 2:
b(n)=b(n-1)+1
b(2)=b(2-1)+1
b(2) = b(1)+1... (2)
Substituting equation 1 into 2
b(2) = b(1)+1
b(2) = 16 + 1 = 17
Hence, The second term in the sequence is 17.

At her birthday party, Ms. Willow would not give her age directly. She said, 'If you add the year of my birth to this year, subtract the year of my 25th birthday and the year of my 55th birthday, and then add my present age, the result is 58.
Answer:
69 years
Step-by-step explanation:
Given that:
Let year of birth = x
This year = 2020
Year of 25th birthday = x + 25
Year of 55th birthday = x + 55
Present age = 2020 - x
Hence,
x + 2020 - (x + 25 + x + 55) + (2020 - x) = 58
x + 2020 - (2x + 80) + (2020 - x) = 58
x + 2020 - 2x - 80 + 2020 - x = 58
-2x + 4040 - 80 = 58
-2x + 3960 = 58
-2x = 58 - 3960
-2x = - 3902
x = 1951
Birth year = 1951
,
Hence, age =
2020 - 1951 = 69 years

48 divided by what equals eight
Answer:
6
Step-by-step explanation:
6 is the answer because 6 times 8 equals 48, so if you divide 48 by 8 then the quotient would equal 6.
The number 48 should be divided by 6 to equal eight is 48 ÷ 6 = 8
To find what number 48 should be divided by to equal eight, we can set up the division equation and solve for the unknown value.
Let's represent the unknown number by 'x':
48 ÷ x = 8
Now, to find the value of 'x,' we can isolate it by performing the inverse operation of division, which is multiplication. We can multiply both sides of the equation by 'x':
x * (48 ÷ x) = x * 8
On the left side, 'x' cancels out with the 'x' in the denominator, leaving us with:
48 = 8x
Next, we can solve for 'x' by dividing both sides by 8:
48 ÷ 8 = 8x ÷ 8
6 = x
Therefore, the number 48 should be divided by 6 to equal eight:
48 ÷ 6 = 8

What is the correct answer for Dean's problem? Explain where he went wrong.
Answer:
The slope is 5/-2.
Step-by-step explanation:
Slope is y1-y2 over m1-m2 (rise over run). The first ordered pair is -2 (m1) and 11 (y1). We then subtract the second ordered pair (4 (m2) and -4 (y2)) from the first.
11 - (-4) = 11 + 4 = 15
-2 - 4 = -6
Remember, slope is rise over run (y over x), so the slope is 15/-6. Now, we must simplify. 15/-6 = 5/-2
Dean went wrong because he thought that slope was run over rise (x over y). If he had switched the two numbers, his answer would have been correct.
