That is 22 and 21:
22 + 21 = 43
if we write equations to find them, we say, numbers are a and b, they are consecutive so:
b = a + 1
a + b = 43
we substitute one in the other equation:
a + (a + 1) = 43
2a = 42
a = 21
then
b = a + 1 = 21 + 1
b = 22
Answer:
B y ≥ 4x + 2
Step-by-step explanation:
1. find slope of the line: (y² - y¹) / (x² - x¹)
(0, 2) and (-1, -2)
(-2 - 2) / (-1 - 0) = -4 / -1 = 4
y = 4x + 2*
*+2 because that is the y-intercept as shown by point (0, 2)
2. the line is solid, therefore the inequality is ≤ or ≥. dashed line would mean < or >
3. the shaded region is on the right side of the line, so the values are greater than. therefore, you use ≥
4. final equation: y ≥ 4x + 2
Answer:
There are 120 students in the choir.
Step-by-step explanation:
Given that:
Number of members who participated in contest = 36
This represents 30% of the total members of choir at the school.
Let,
x be the number of total sutdents
30% of x = 36
0.3x = 36
Dividing both sides by 0.3
Hence,
There are 120 students in the choir.
Is it a decimal? If you mean 2.56 and 3.21, they are 2.6 and 3.2 rounded to the nearest tenth. To the nearest whole number, they would both be 3.
If they are whole numbers, rounded to the hundreds place would be 300 for both. Rounded to two digits would be 260 and 320, respectively.
Please clarify what you mean.
