Answer:
<em>Tadeo Volunteered for 12 hours while Dylan volunteered for 2 hours</em>
Step-by-step explanation:
Let the total number of hours Tadeo volunteered be x
Let the total number of hours Dylan volunteered be y
If together they volunteer at a total of 14 hours, then;
x + y = 14 ...... 1
If<em> </em>Tadeo Volunteered at the library six times as many hours over the weekend as Dylan, then;
x = 6y
Substitute x = 6y into 1;
6y + y = 14
7y = 14
y = 14/7
y = 2
Since x = 6y
x = 6(2)
x = 12
<em>Hence Tadeo Volunteered for 12 hours while Dylan volunteered for 2 hours</em>
Answer:
They are all true
Step-by-step explanation:
1. 3² +4² = 5²
3x3 + 4x4 = 5x5
9 + 16 = 25
25 = 25
-----------------------
2. 6² + 8² = 10²
36 + 64 = 100
100 = 100
------------------
3. 9² + 12² = 15²
81 + 144 = 225
225 = 225
-------------------
4. 5² +12² =13²
25 + 144 = 169
169 =169
-------------------
Answer:
x = -2, 1/2
Step-by-step explanation:
Step 1: Isolate everything to 1 side
2x² + 3x - 2 = 0
Step 2: Factor
(2x - 1)(x + 2) = 0
Step 3: Find roots
2x - 1 = 0
2x = 1
x = 1/2
x + 2 = 0
x = -2
It meter and gram because it not kilometers or kilograms
