Answer:
120 degrees so answer b
Step-by-step explanation:
the opposite angles in the shape are equal so <klm = <kjm. this means the answer is the same as the sum of the other sides so 78 + 42 which is 120 degrees
First, find the function that represents x and y.
x is the number of 8 oz jars
y is the number of 16 oz jars
function: 8x + 16y = 240
x-intercept: y = 0 => 8x = 240 => x = 30 => (30,0)
y-intercept: x = 0 => 16y = 240 => y = 15 => (0, 15)
Answer: (0,15) and (30,0)
Answer:
- Martin is 40 and Ada is 14
Step-by-step explanation:
- Martin's age = m
- Ada's age = a
<u>Martin is two years younger than three times his daughter Ada’s age:</u>
<u>The sum of their ages is 54:</u>
<u>Solving this equation for m:</u>
<u>Eliminate m:</u>
<u>Solve for a:</u>
- 3a + a = 54 + 2
- 4a = 56
- a = 56/4
- a = 14
<u>Find m:</u>
Martin is 40 and Ada is 14
Y = ax + b;
0.89 = a * 2 + b and 2.09 = a * 5 + b =>
=> 2.09 - 0.89 = a * 5 + a * 2 + b - b => 1.20 = 3 * a => a = 1.20 / 3 => a = 0.40;
b = 0.89 - 0.40 * 2 => b = 0.89 - 0.80 => b = 0.09;
y = 0.40x + 0.09 => 0.40x - y + 0.09 = 0 is the linear equation.
10. Not sure what the question is. Looks like it could be to write 9/5 in decimal form? In that case, we have 1/5 = 0.2, so 9/5 = 9*0.2 = 1.8
11. 
. If we round to 5 decimal places, the approximate value is 52.23232
12. By long division, we can show that 
. In repeated decimal notation, that's
